How to flash STM32CubeDemo_STM32769I-DISCO_V1.0.1.hex on board with Linux ?

[olivier.scalbert]

I am trying to flash STM32CubeDemo_STM32769I-DISCO_V1.0.1.hex into the board, under Linux, with st-flash. And it does not work:

$ st-flash --serial /dev/ttyACM0 --format ihex write STM32F769I-Discovery/Demonstration/Binary/STM32CubeDemo_STM32769I-DISCO_V1.0.1.hex

st-flash 1.5.1-38-gc3577b5

2019-09-30T15:13:16 ERROR common.c: addr too high

stlink_fwrite_flash() == -1

What should I do ?

Thanks

Looks like the hex file is interpreted as binary file. But even if it would be interpreted correctly: The hex file in question contains not only the contents of the internal flash, but also of the external NOR flash on the board. I don't know whether st-flash can actually deal with that external memory, probably not.

Either use STM32CubeProgrammer with a suitable external loader (should be included in the package) or use http://openocd.zylin.com/#/c/4321/.

Hi Andreas,

Thanks for your help.

I have never used openocd. Time to do it now !

I have installed it on my debian buster, but I think I need to download your version and compile it.

But how to I get your repo (git clone ???).

Thanks !

[Andreas Bolsch]

Yes, clone (master!), and afterwards download the patchset and apply the patch. On linux, the build procedure should be straightforward.

[olivier.scalbert]

Ok it works now !

For those, like me, who are not fluent with openocd, here are the different steps.

I have patched, compiled and installed openocd

I get the board serial:

$ st-info --probe

Found 1 stlink programmers

 serial: 303637314646353635323531383837303637303135313133

openocd: "\x30\x36\x37\x31\x46\x46\x35\x36\x35\x32\x35\x31\x38\x38\x37\x30\x36\x37\x30\x31\x35\x31\x31\x33"

 flash: 2097152 (pagesize: 2048)

  sram: 524288

 chipid: 0x0451

 descr: F76xxx device

I create a openocd.cfg file:

source [find interface/stlink.cfg]

source [find board/stm32f769i-disco.cfg]

hla_serial "\x30\x36\x37\x31\x46\x46\x35\x36\x35\x32\x35\x31\x38\x38\x37\x30\x36\x37\x30\x31\x35\x31\x31\x33"

Then I load the hex file:

$ openocd -f openocd.cfg -c "program .... path to /Cube_FW_F7_V1.4.0/Projects/STM32F769I-Discovery/Demonstration/Binary/STM32769I-DISCO_DEMO_V1.0.0_FULL.hex" -c "reset" -c "run"

7m46.658s later the board is up and running !

Thanks Andreas !

I also be able to load the new Qt demo for mcu.

So it is a good day !

;)

[Andreas Bolsch]

That's good. BTW: You don't need an extra cfg-file. Just '-f board/stm32f769i-disco.cfg' should be sufficient, as long as only one ST-Link is attached.

Using STLink-V3 would give *MUCH* higher speed, but I don't know if is possible to isolate the SWD from the onboard STLink and attach an external easily.

Checked this only for stm32f746g-disco, and there it's somewhat delicate ...

Thanks again Andreas !

Hi,

Still a little problem with "verify":

$ openocd -f board/stm32f769i-disco.cfg -c "program STM32Cube_FW_F7_V1.4.0/Projects/STM32F769I-Discovery/Demonstration/Binary/STM32769I-DISCO_DEMO_V1.0.0_FULL.hex verify reset exit"

Oh, that's a wrong read command in QPI mode, probably I deleted the wrong line when removing the SPI branch in the cfg file. Replace in the cfg

mww 0xA0001014 0x0F003F13                              ;# QUADSPI_CCR: FMODE=0x3, DMODE=0x1, DCYC=0x0, ADSIZE=0x3, ADMODE=0x1, IMODE=0x1, INSTR=READ
