Testing facilities Discussions

[mcuee]

It will be good to create a list of testing facilities for the volunteer testers: OS, Programmers and AVR chips.

OS: Windows (not so sure who have ARM64 Windows machine), Linux (x86_64, ARM64), macOS (Intel or ARM64), FreeBSD, etc

Programmers: Microchip programmers supported by Microchip for AVR chips (PICKit 2 is not one of them); non-Microchip programmers

AVR chips or development boards: Microchip official boards will usually have the programmer built-in. Arduino boards will usually have the bootloaders.

[mcuee]

For me I have access to Intel x86_64 Windows 10/11; Mac Mini M1 (ARM64) and Linux (Intel x86_64 and ARM64 with Raspberry Pi 400). I can also test FreeBSD, OpenBSD and NetBSD using virtual machines inside Windows or Proxmox V7.4 or v8 (low power Intel CPU based mini PC).

[dl8dtl]

My main development system is FreeBSD, so for sure, I'm going to test this.
I've also got access to Linux systems including an elderly Raspberry Pi (important for linuxgpio and linuxspi), and Macs both M1 and x86_64.
Enumerating all the tools and devboards I've got access to is way too much here. It would be easier to explain what I don't have :-), e.g. the PICkit4 that was recently mentioned I don't have.
I theory, I could access an old UltraSPARC machine with both FreeBSD and Solaris, but it's quite dated, and can hardly be revived.

[mcuee]

@MCUdude
I think you have quite some programmers and tools as well, in particular, you have the official Microchip PICKit 4 and SNAP as well as AVR Dragon and genuine STK500 kits.

[mcuee]

In theory, I could access an old UltraSPARC machine with both FreeBSD and Solaris, but it's quite dated, and can hardly be revived.

Wow, avrdude even supports Solaris. Solaris does have libusb-1.0/libusb-0.1 support (they also have openusb) for Solaris x86, no idea about Solaris UltraSpac. So not sure anyone have tried the USB programmers there.

[dl8dtl]

Wow, avrdude even supports Solaris.

At least, it used to. I haven't tested the current release there.

[UltraSparc] So not sure anyone have tried the USB programmers there.

I'm pretty sure I once tested at least an AVRISPmkII on the UltraSPARC platform. After all, these blade server machines don't have any other connectors but USB. (Despite, Solaris even offers a well-defined parallel-port API, so we support parallel-port adapters on Solaris, like we do on Linux and FreeBSD. Probably no longer relevant these days. :-))

[stefanrueger]

It will be good to create a list of testing facilities

Brilliant idea. This is very, very helpful.

Automation is key. Something along the lines of "tricky" .hex files (with holes, etc) for flash upload/download (one of each relevant class of AVR?), automated EEPROM r/w tests, etc.

[dl8dtl]

Automation is key.

Do you think about anything that integrates into Github's CI?

That's probably going to be pretty hard for the entire amount of hardware (AVR devices vs. programmers) in question. However, I could probably set a Raspberry Pi aside and connect a bit of stuff to it, that can then be attached to the CI. I have no experience with these processes though.

[stefanrueger]

Do you think about anything that integrates into Github's CI?

I haven't thought that far! In the first instance I thought of neat little shell scripts that can test paged flash and eeprom r/w, byte read/write for non flash (or when it's the only method), maybe even write a few safe fuse bytes under carefully choreographed scenarios etc.

But yes, the thought of an array of 45 programmers times 5 different MUCs (one per family) that are always connected to an RPi and will rush into action every time someone commits so much as removing a typo in a comment has something! It's just 225 devices, and with an estimated power of 2 W/device will "only" cost a few thousand USD/GBP/EUR per year to run... :) OTOH, if there was a clever way of multiplexing a dozen of key programmers with 5 MCUs through an interface that the RPi can control then this would be the most wonderful whacky (in a good sense) CI that certainly I've come across...

[mcuee]

It is always difficult to carry out CI when HW is involved. There are similar discussions in libusb, libusbdotnet and pyusb.

Ref: pyusb discussion
pyusb/pyusb#235

In the end, emulated USB device is kind of used in libusb.
https://github.com/libusb/libusb/blob/master/tests/umockdev.c

So one way is to develop a "Software emulated hardware" to test avrdude, but it is probably not easy.

[mcuee]

I am located in Singapore and I know Chinese so I usually buy stufff from Taobao (part of AliBaba group).

For example I bought the JTAG ICE clone from Taobao for about US$7.64 (RMB 45 for the unit + 7% GST for Singapore + RMB 3 sea shipment = RMB 51.15 = about US$7.64 ). Sea shipment is cheaper but it will take me about 1 month to get the stuff. So sometimes I use local online stores like Shopee or Lazada, which has faster shipment (sometimes the stock is already in Singapore, sometimes it is from China).

You can probably buy from AliExpress (part of Alibaba group) which offers global shipment. Or you can look at other places like Amazon.
The AliExpress links below are only for reference as I do not have experiences with the shops. You may need to look at the reviews closely to select the shop to buy.

A quick search shows around US$7 to US$20 for the JTAG ICE clone. My one is the square box type and not the usbasp type.
https://www.aliexpress.com/w/wholesale-jtag-ice-avr.html
https://www.aliexpress.com/item/32222264745.html

Similar search for AliExpress for AVRISP mkii. My one is at about US$15.
https://www.aliexpress.com/w/wholesale-avrisp-mkii.html
https://www.aliexpress.com/item/32960161527.html

The FT232RL with AVR ISP pin header (blue one) is at US$1.44 plus shipment.
https://www.aliexpress.com/item/32273550144.html

[mcuee]

For ATxemga break-out or development board, there are not many choices. I found the following from mcuzone. I have bought the ATxmega32D4 mini board from their Taobao shop (which has more options than their AliExpress shop) but I have not figured out how to progam using the PDI interface with the AVR Dragon or the AVRISP mkii clone.

Nice link here for DIY programmers, including various updi versions like serialupdi, updi-HV, and also usbasp/usbtinyisp
https://github.com/wagiminator/AVR-Programmer

1. usbasp seems to be the most popular low cost USB programmers. There seem to be add-ons to support PDI and maybe updi.
   Ref: usbasp xmega pdi enhancement #1024

There are many usbasp clones out there -- mostly based on the original design using Atmega8/8A, but there are others using ATmega88/88A. In particular, there are Chinese clones (usually called USBISP) which are using ATmega88 and present as USB HID device. Those clones are using ProgISP and not compatible avrdude. However, some of them can be upgraded using the FW here (USB composite FW with WinUSB and HID). I was able to change one of them to use usbasp FW. But the other two clone failed. You need to short two test PCB vias and then use another programmer to upgrade the FW.
https://github.com/dioannidis/usbasp/tree/master/bin/firmware (usbasp.atmega88.2011-05-28.hex)

2. usbtinyisp is also popular. There are clones using ATtiny2313 (usually discrete DIP part, with 10pin and 6-pin ISP connector) and then there are clones using ATtiny44 and ATtiny45.

3. SerialUPDI/JTAG2UPDI can be made cheaply from USB to TTL converters by adding a few components.
   https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md

[mcuee]

STK500 schematics are openly available so there are also many clones (usually just the programmer portion). Very few of them will support HVSP/HVPP.
Ref: https://mechatronics.me.wisc.edu/labresources/schematicsNManuals.htm

But I can see there are different clones claimed to be STK500v2 compatible but may not exactly the same (some of them do not even use AT90S8535/ATmega8535).

Waveshare seems to be the more famous clone for STK500v2/AVRISP (ISP portion, no HV programming)
https://www.waveshare.com/wiki/USB_AVRISP_CH

Then there are various clone schematics for AVR JTAG ICE.
https://scienceprog.com/build-your-own-avr-jtagice-clone/
https://github.com/vyivanov/AVR-JTAG-ICE-mkI

There are also clones of AVRISP mkii. For example, Waveshare AVRISP XPII seems to be the more famous one. But there are cheap ones which seem to work fine as well.
https://www.waveshare.com/wiki/USB_AVRISP_XPII

There are also clones of JTAG ICE mkii (not many). But the price is not cheap.
https://www.waveshare.com/wiki/USB_AVR_JTAGICE_XPII

MCUzone has clones for STK500v2, JTAG ICE, and JTAG ICE mkii. They seem to have the cheapest JTAG ICE mkii clone at RMB480 plus GST + shipment (about RMB516.6 or US$77 to reach me by sea shipment).
http://www.mcuzone.com/index.htm
http://www.mcuzone.com/shop/?gallery-18.html (in Chinese)

Probably it is good enough to own an official PICKit 4 at US$77 (or SNAP at US$34.09) than to look at JTAG ICE mkii clone. Most of the people will probably not need Atmel-ICE or Power Debugger.

Off topic: Do you think Microchip would either donate or let one of us spare time Avrdude developers borrow some hardware to ensure that Avrdude properly supports the hardware? There's a few issues we can't work on without testing it on actual hardware:

• The Power Debugger hasn't gotten much love, and there's a few features that could be added to Avrdude terminal mode.
• Potential issue (#404) where xmegas with 256kB flash or more fails if the program is greater than 128kB in size
• Unconfirmed issue with A4U devices (#289)
• 256A3BU hangs, when programming or reading device signature (#337)

[mcuee]

@MCUdude
For the xmega, Microchip seems to only offer XMEGA A1U Xplained Pro with ATxmega128A1U and XMEGA-E5 XPLAINED with ATxmega32E5. Probably they are not good enough for #337 and #404.

Not so sure if they have some in-house boards with ATxmega256A3U or similar (for #337 and #404) and ATxmega128A4U or similar (for #289). Probably we have to buy from places like AliExpress.

Edit: Actually Microchip has the ATxmega256A3BU based dev board.

Google shows that AliExpress has the ATxmega boards available.
Reference: ATxmega256A3U development board, roughly US$56 + Shipment + tax.
https://www.aliexpress.com/item/4001166867043.html

BTW, the same shop also has the cheaper ATxmega32A4 breakout board.

@mcuee I've been in touch with Jan Egil, and it looks like I'll receive some test gear sometime in August/September. I'm not sure what I'll receive though.

That is great.

I have never tried to use HV programming previously. Today I tried to use it using my STK500 clone (with HVPP sockets for M16/M32 and M8).

For DIY UPDI programmers, either jtag2updi or serialupdi can be a good choices.
jtag2updi (please use latest version)
https://github.com/ElTangas/jtag2updi

serialupdi
https://github.com/SpenceKonde/AVR-Guidance/blob/master/UPDI/jtag2updi.md

One of the better design of serialupdi programmer is from @MCUdude. He has also the microupdi programmer.
https://github.com/MCUdude/MegaCoreX#updi-programmers

[mcuee]

Basically for average avrdude users, I think usbasp, usbtinyisp, stk500v2 clone or avrispmkii clone will be good one to get started with classic AVRs. avrispmkii also works with xmega. Of course, cheaper ones like FT232RL based programmer can be a good choice as well (a bit slow). Cheap Arduino Uno/Nano clones can be made into good progammers as well (Arduino as ISP, AVR910 or STK500v2).

For UPDI, Microchip SNAP, PICKit 4, jtag2updi (using Uno or Nano clones) and serialupdi are good ones to have.

Down the road, probably Microchip SNAP and PICKit 4 will be the preferred official tool for all AVRs. usbasp, usbtinyisp, jtag2updi and serialupdi will be the good unofficial tools to have.

[mcuee]

I have a AVRISP mkii which did not work. Today I used Microchip Studio to upgrade the FW from 1.23 to 1.24 and now it works.

My main host side stuff.
Updated on 3-Oct-2023.

1. macOS ARM64:
   Mac Mini M1 2021. My old Mac Mini 2011 was dead in 2019 so I cannot test old macOS releases.

2. Windows 11 and Linux x86_64:
   Acer Swift 3 laptop, 2021 model -- dual boot, Windows 11 and Ubuntu Linux 20.04 (Intel Core i5-1135G7, 16GB RAM, 512GB SSD)
   I have FreeBSD/OpenBSD/NetBSD VMs using VirtualBox as well but sometimes USB stops working inside the VM after upgradiing VirtualBox.

3. ARM Linux using ARM SBCs
   I usually use my Raspberry Pi 499 as it is faster than my other ARM SBCs. I have Raspberry Pi 3B+ and Raspberry Pi 2 (early version) as well and a few other OrangePi boards. This runs Raspberry Pi OS (32bit/64bit) or Ubuntu 64bit Linux.

4. Linux x86_64 physical machine, and Linux/BSD VMs: using mini PC powered by low power Intel CPUs.

Intel J4105 and Intel J4125 Mini PC running Proxmox Virtual Environment (PVE), Linux/BSD VMs and LxC Linux Containers.
Intel N4200 mini PC running dual boot Ubuntu 22.04 and Debian 12.
I have also ordered two new Intel N100 based Mini PCs.

The Intel J4105 mini PC has 4 gigabit ports and I play with home networking stuff using it with a WiFi 6 Access Point attached to it. You can see that I am running OpenWRT now and two LxC conainers (one with Pi-hole and the other with Adguard Home).

But it also runs BSD and Linux VMs so that I can carry out tests of avrdude and other open source projects as well. USB passthrough works better in PVE than VirtualBox. I am slowly building up PVE8 on the Intel J4125 mini PC (single 2.5Gbe adapter).
