STM32F410RBTx not supported

[thebiguno]

Hello all,

I am trying to program an STM32F410RBTx chip with stlink, and it is failing with error:

wyatt@behemoth:~/stm32f410/led$ /opt/stlink/st-flash write led.bin 0x8000000
2016-05-18T21:59:59 INFO /src/common.c: Loading device parameters....
2016-05-18T21:59:59 WARN /src/common.c: unknown chip id! 0x10006458

Looking at include/stlink/chipid.h I can see that there is no entry for ID 458. Unfortunately I am not clear on the different parameters in src/chipid.c to add this chip myself, as I am quite new to ARM programming.

I am programming the chip on a custom board via the NUCLEO F411RE dev board in target mode. I know the programmer works, as I can program it correctly using st-link. I know the custom board + chip works as I can program it via the Nucleo in USB mass storage mode.

I would prefer to use this command line tool for programming, as it integrates with Makefiles better than the USB mass storage programming mode; plus it will open up my options for other programmers (not just using the Nucleo).

• Programmer/board type: NUCLEO F411RE board in target mode (CN2 not bridged)
• Operating system: Debian Jessie
• Stlink tools version and/or git commit hash: 1.2.0-27-gad39787
• Stlink commandline tool name: st-flash
• Target chip (and optional board): STM32F410RBTx

Output:

wyatt@behemoth:~/stm32f410/led$ /opt/stlink/st-flash write led.bin 0x8000000
2016-05-18T21:59:59 INFO /src/common.c: Loading device parameters....
2016-05-18T21:59:59 WARN /src/common.c: unknown chip id! 0x10006458

Expected/description:
st-link does not appear to support the STM32F410RBTx chip.

Could you test with 9c635e4 I have not tested it on real hardware.

[thebiguno]

Sorry for the delay in testing, yesterday was crazy.

Anyway, it is getting closer, but not quite there yet. This is the output now:

Thanks!

There is something wrong now with selection of the correct flash loader because the coreid is not recognized.

[thebiguno]

Is this something that you need from me? I would be happy to help but am not clear on what you need.

[xor-gate]

I'm not sure yet either because the flash loader mechanism is build by other people. I'm trying to figure out why it doesn't recognized correctly. What it does: st-flash writes a program (flash loader) in to SRAM and then runs it. Then the interaction is done using the flash loader to program the internal memory.

[thebiguno]

Gotcha. When you figure it out, let me know what I can do to help.

https://github.com/texane/stlink/blob/1507e34dd6455636724bb68b7c5c2253dd2fb77b/src/common.c#L1620-L1622

We need to add the F410 chipid to that flash-loader selector, hopefully fixed here:
8da1467

As seen now, the chipid doesn't select the flash-loader itself and is semi-hardcoded in common.c currently.

Let me know if it works (or not)

[thebiguno]

Beautiful!

This looks to be working as far as I am concerned. Thank you very much for your quick fix!

Cheers

Very nice, have fun 👍. I have not 100% verified the chipid parameters are correctly set. But the chip should have 32KB SRAM and 128KB flash (16KB pages).
