Compiling for different channels

[danielefrigo]

Hi
I'm trying to compile hex files for channels different from the default one.
I'm using MySBootloader dev branch and the provided boards.txt

I changed the channel here and the board frequency to 8MHz here.

I then compiled (simply running a Make), no errors, but when I flash the obtained hex file on my Arduino (Pro Mini 3.3V 8MHz) it hangs and I'm not able to upload any sketch.

Thanks in advance for any help or suggestion
Daniele

I am very interested in your effort. Have you had any advances?

I'm using a different channel because of interference and of course FOTA is not working.

Can you share with me your development environment? I don't seem to be able to compile this.

[guillebot]

Forget it. I compiled it already. Let's go testing.

Holy crap. It's updating. I just changed the (76) channel and it works.

Beats me where it's getting the node id from. Does the bootloader reads from the main sketch? (if so, why isn't reading the rf channel also)

Please @tekka007 a little insight? Thanks

Could you share with what did you change in order to get it work? Which Arduino are you using? Il giorno mar 15 gen 2019, 23:06 Guillermo <notifications@github.com> ha scritto:

I'm using Arduino Uno right now. Soon I will test all this with arduino pro mini 3.3V. I burned the bootloader with Arduino IDE on the first try, and then I burned it with AVRDUDESS software, on a USBASP programmer. Don't know if is there a difference. Both seems to use the avr software on the PC. Regarding the software changes, I just changed (76) with (100) in MYSBootloader.c Good luck!

Could you please describe the steps you did to be able to compile? Do I need to place this folder in some specific location?
I have Arduino installed on ubuntu 16.04 and when I try to run make in the project folder I get:

../arduino/bin-linux64/bin/avr-gcc: not found

[guillebot]

Just make. You don't have the avr devel tools, which includes avr-gcc

Just install them and it will compile.

Or look at my repo, I compiled all the channels and all the clock frecuencies.

As far as I can tell I have avr-gcc installed, it came with the arduino installation. Still not working.
What is curious to me is that the script is looking for avr-gcc in some arduino folder. So it expects arduino to be installed..
Thank you for suggesting your pre-compiled hex, just that I am using a custom hardware with the CE and CSN signals on other pins and I want to compile for that.

[guillebot]

You should probably check the PATH variables in the script. Put your avr-gcc path there. I had to change it also.

Check my Makefile and the script I use to compile them all.

Just check the latest version. Some user asked me for multiple POWER_LEVELs also.

I'm using this on an arduino pro mini @8MHz on a non standard channel, RF24_PA_MAX, and works great.

@guillebot Thanks so much for this!

[guillebot]

@guillebot Thanks so much for this!

Thank to @scalz! I'm just compiling.

Good luck

With merging #36 I think this issue is resolved. Feel free to reopen if that's not the case.
