Unable to update the firmware #24
Comments
|
Same problem with TFT35 V2.0 .... only icons and fonts are updated :-( . Any specific BIN file name? Or a requirement other than copying to the card root? |
|
I renamed it to BIQU_TFT35.bin and it worked |
|
for me ..... renaming it to BIQU_TFT35.bin ... no change .... still firmware upgrade has not taken place :-( |
|
you tried BIGTREETECH_TFT35.bin ? |
|
yes, I tried a lot of file names, including BIGTREETECH_TFT35 ... the upgrade was still unsuccessful. I'm clueless. Installation instructions absolutely useless :-( |
|
I am also facing the same problem, cant upgrade TFT35 firmware. It updates the icons and fonts but not the firmware. |
|
Connect a ST-link. Read out the bootloader and save. Open the file in a HEX-editor. Search for readable strings containing ".bin" and ".cur". And you'll get the right name- completely without guessing. |
|
Same issue here with my new TFT35 2.0 running 2.0.20. I can update the TFT35 folder but I can't install new firmware |
Unfortunately, I did not get a simple answer either here or directly from BIQU. It looks like product support isn't worth anything. |
|
I believe you are supposed to just name it |
|
please download in here https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware/tree/master/Copy%20to%20SD%20Card%20root%20directory%20to%20update\ |
I have already understood this, but after inserting the BIQU_TFT35_APP1_V2.0.22.bin file on the SD card, inserting the card into the TFT35 V2.0 and pressing the reset button, the firmware simply does not update ... Paradoxically, when you insert the TFT35 directory with icons and fonts, Updating icons and fonts runs without a problem. |
That is exactly the same issue I have. It doesn't matter if I use the precompiled or if I compile it myself. I have tried several different filenames including the ones suggested in this thread. I bought two of these displays and it is the same problem with both |
|
Do you have a burner like stlink? Maybe I can send you a bootloader and try to reburning the bootloader? |
I have a couple of nucleo boards with integrated stlink that I should be able to use. I'll give it a try |
I have ST-link V2 ordered, but not yet arrived .... I can try it afterwards |
|
BIQU_TFT35_V2.0_bootloader.zip |
|
Is it expected the bootloaders rename the *.bin files to *.cur when flashed? |
|
Succes! After uploading the new bootloader it worked! |
|
@AnHardt it doesn't change the firmware to .cur you will need to delete it or rename it afterward if you don't want to reflash your board at each reboot ( at least for tft35 v1.2) |
|
@EnnajimiYassine I used the boot loader first and flashed it with stink utility
And then I just used the precompiled file: BIQU_TFT35_APP1_V2.0.22.bin |
|
Thanks for sharing the info! It may help the others |
|
Ok, cool ! I have the same issue, but how can i do if i don't have any flashing board... I presume i'm not alone in this case... I'm a noob in programming, i never do that. Can I do it with an Arduino Uno ? Don't laugh, i'm a really noob !!! |
|
I need help too. :/ |
|
@bigtreetech I think you should post some firmware names, so those who don't have an stlink can update their firmware. Because from what I understand we're supposed to update it with sd card (that's what your GitHub says) and not via stlink .... |
|
I have a same problem as @blindMoe with my TFT24-V1.1. |
|
On my tft 24 v1.1 I found that on a exp1 exp2 config, no serial(for my case,didn't test with). to be able to flawlessly flash new firmware you have to disconnect exp2 to make it work. I think the feedback of the "sd card presence" pin interfere with the upload. |
|
@bigtreetech finally I've managed to flash my unit that touchscreen wasnt working and now Is stuck on calibration touch screen and fails everytime i do the red dots (correctly pressed!). what's next? |
|
@Sthopeless Start-up through the calibration screen seems normal after an update (Tested on TFT 3.5 and TFT24). |
|
@GenaUser I know it is a normal procedure on they're TFT's but this one is constantly failing the calibration, I even tried with touch pen but fails all the time |
|
I'd start by unlocking the board (you can find a guide to that here
https://nathan.vertile.com/blog/2017/03/05/unlocking-stm32-chips/
if you are running OSX I can share the commands I use to connect using GDB):
Start Debug Server:
~/Library/Arduino15/packages/STM32/tools/STM32Tools/2017.9.22/tools/macosx/stlink/st-util
Launch GDB:
~/Library/Arduino15/packages/STM32/tools/arm-none-eabi-gcc/8.2.1-1.7/bin/arm-none-eabi-gdb
Connect:
target remote localhost:4242
THEN run the unlock/reset/halt, and after that, you should be able to
program it all.

Thanks for the response guys. I since sourced a very stable power supply.
As for mass erasing, I forgot to include that it did erase the chip as
everything is Zero'd out and the flash size is "Unknown" but it gave the
readout protection during erase and is still giving the error. Some
research on google showed how to disable in in st-Link but when I try to
disable it, it gives me the error "Could not set Option bytes! Please reset
the target and retry."
Unfortunately, I've tried at least 30 times. I will not give up 😢
I've used up too much time diagnosing. Everyone's recommendations whether
it be sending 3v3 to the Boot0 and using ttl to every possible setting in
st link, I have a hardware issue somewhere. I can't flash any bin or hex
files, erasing actually erased the data but kept the write protection, 5.1v
constant power, and nothing. The RS232 port is completely disabled so no
more TTL. The SWD can read but that's all it can do.
For reference, the only way I can connect to the board in st link is to
have SWD, Hot Plug modes. No other modes work. Reset button also does
nothing anymore.
My replacement will arrive on Saturday due to the holiday season. I will
get a v3.0 instead of the 2.0 as I don't even want to see the thing
anymore. Feel so damn defeated and don't even feel like completing this 3d
printer anymore. Thanks guys.
Look up @xC0000005 <https://github.com/xC0000005> If anyone can bring
life back to a board he can! https://github.com/xC0000005

I made some progress. I learned to use OpenOCD which took a while as I had to also learn to use PuTTY. I also got it to connect to my main pc. When I try to unlock, I get the error that my flash size failed to probe and it puts an incorrect size of 512k. I'll have to learn the Flash Bank command but I have no idea what FLASHNAME they are talking about. The other main error is "Target not halted" this prevents almost all commands from working. Adding halt in the config and manually executing it just causes a timeout. I'm slowly chipping away at it. My goal is to get it working by tomorrow when my replacement arrives. If I can fix it, I'll use it on my old trusty 3d printer. Thanks for the information. |

The "target not halted" problem is most likely due to the .1uF capacitor on the reset pin of the MCU. It adds too much delay to the reset process, causing openOcd to time out. The simplest solution is to temporarily remove it, so that you can use the ST-link to re-flash the boot-loader. |
|
I'm actually more concerned that the ST link can't probe correctly. If you
use the ST-info utility, can it ID the chip and info with --probe?
That said, SWD can (and does) get hosed by clock config, which is why being
able to hold reset is important (acquire under reset usually works). If
BOOT0 is held at 3.3v TTL, it should be booting from system memory, not
flash, and that clock config will usually work.

Alternatively, you can try to configure openOcd to wait longer for the MCU
to respond after a reset is issued.

Probe and most other SWD functions will not work if the reset pin is interfered with by the capacitor. I've encountered this many times on other boards. Removing the cap is an easy fix for anyone with some soldering skills. |
|
I was experiencing the same problem (unable to update from V1.2.6 on V1.2 hardware), and renaming the BIQU_TFT35_V1.2.25.2.bin firmware to BIQU_TFT35.bin worked ! |
|
I had a lot of trouble trying to get the bootloader to load onto the board. The error message in FlyMCU read something like ""program space must be in either (...etc" |
|
To be able to update the firmware you need a really specific SD format settings, It need to be less than 8GB, have a Primary MBR Partition marked as Active in Fat format |
|
@bigtreetech |
|
Can I also have the TFT24 boot loader please, Thanks |
|
i have the same problem with TFT 3.5 V3, Illegal flash app, its my second board with the same problem I used the right file but its impossible make it work |
|
Hi, it seems like I have similar problem, I flashed my TFT24 with v1.1.26.x.bin and everything went well but after that, I wanted to make some more changes, but I cannot flash any new firmware. Bootloader goes through the update process, but nothing changes. I tried different firmware versions including precompiled ones and nothing changes. I tried renaming .bin file. I tried @poisson21 advice to disconnect EXP2 but it didn't help. I guess there is a bug in new firmware that prevents flashing updates. Since I have ST-LINK v3 I guess I can clear it and reflash the bootloader, does someone have bootloader for TFT24? |
|
@draon7 Is the tft24 still able to see the sd card files when you press the "print" icon? Does the bootloader change the name of the .BIN file to .CUR on the sd card? |
|
At least for me, if I turn the printer with a sd card inside, with Gcode files, say illegal flash, and if you forgot the sd card inside, you must reflash again with config.ini, tft35 "bmp files" and bin file. A big problem, I hope the next update BTT solve the problem. |
|
Please help the community and close the ticket now that it is one year old Thank you |
From what I've read, yes, as long as the .bin file is utilized correctly by the printer once, it changes the extension to .CUR. |
|
Who dealt with this problem, can you describe in detail the entire process of resuscitation of Bigtreetech TFT35 V2. 0 |
|
This ticket is very old and the owner does not respond anymore. It is unlikely that someone will answer this further, now that I stop watching it. Please start a new ticket in case you have a problem with updating the firmware of your TFT and make sure to read this before doing so: https://github.com/bigtreetech/BIGTREETECH-TouchScreenFirmware#connect-the-tft-to-the-mainboard Thank you |

Very thanks a few days ago I was complaining with my tft and disconnecting the exp 2 I was able to update it |
|
I have a problem with my TFT35 V3.0.1, the firmware wont update and none of the file names for the .bin file is working. I can get the fonts and language to change too, but its only the firmware file |

This issue has been automatically locked since there has not been any recent activity after it was closed. Please open a new issue for related bugs. |
and others
I'm unable to update the firmware of my board tft35 ( hardware : V1.2, firmware : 1.2.6)
when i put the firmware on the SD card and reset nothing happen ( no firmware update), but when i put the bmp and font they get updated ( but still not the firmware)
Can please some one help ?
