SRST Error & OpenOCD Warning #11

Closed astroesteban closed 3 years ago

astroesteban commented 3 years ago

Hey yall,

I'm having a bit of an issue with flashing my TM4C123 board. The first is the warning from OpenOCD to switch to board/ti_ek-tm4c123gxl.cfg. Is there a way I can configure that in platformio? Or is that fixed in a newer release?

Second, I get a bunch of Error: SRST error but the board does get flashed. I can even launch the debugger and step through the code. Is this error something that can be easily fixed on my end?

Have you managed to fix the problem?

astroesteban commented 3 years ago

Yes I did. Thanks! I just updated the config file OpenOCD used.

MartinPetrei commented 3 years ago

@astroesteban can you give some details about how to update the config file for OpenOCD? Thanks.

amidg commented 3 years ago

@astroesteban can you please, elaborate on you solution? I have TM4C123GH6PM Tiva-C board and I have updated my .json file in the PlatformIO eventually creating another custom board variant. Now I just get SRST error with no upload.

astroesteban commented 3 years ago

Hey @amidg all I did was change the configuration file OpenOCD loads from board/ek-tm4c123gxl.cfg to board/ti_ek-tm4c123gxl.cfg. You can see more information on how that's changed here. The System Reset (SRST) is a pretty finicky thing. You can read up about it here.

Since posting this issue OpenOCD released version 0.11.0 which seems to be working great for me. I don't know what version PlatformIO ships with but if there's a way to upgrade to the latest OpenOCD (found here I'd recommend you do that too.

Let me know if that works for you. I've since switched over to a CMake + VS Code + Cortex Debug (with OpenOCD & GDB) setup.

I have updated both Windows and Linux machine with the OpenOCD 0.11.0 from your link, still the same result. I get SRST error still. I have also updated ti_ek-tm4c123gxl.cfg file with the following lines to test what VS Code terminal will show: source [find interface/ti-icdi.cfg] echo "interface ti-icdi.cfg is working, OK!"

transport select hla_jtag echo "hla_jtag working ok!"

set WORKAREASIZE 0x8000 set CHIPNAME tm4c123gh6pm echo "board MCU design is set correctly"

source [find target/stellaris.cfg] echo "stellaris.cfg is working correctly"

It does not even reach that point because SRST error seems to appear before this file is even executed. Any thoughts?

@amidg Gotcha. I ran that on Mac OS and it seemed to fix it. I'll give it another try this weekend and report back to you.

I kinda figured out what the problem is. After uploading, OPENOCD resets the MCU, I noticed if I activate PLL the reset stage fails. So, I added this line to platformio.ini:

upload_command = openocd -f /usr/share/openocd/scripts/board/ti_ek-tm4c123gxl.cfg -c "program .pio/build/lptm4c123gh6pm/firmware.elf verify exit"

And I do the reset myself on the board.
