STM32FP - direct flashing is reverted
@UweBonnes make great work, but now I see that his patch don't work with STM32F0 (I don't make tests with other FP MCUs before merging) Currently is the code reverted to flashing using microcode. Also I don't understand why this e72aca9 ? because this stop currently running program in MCU but don't restart all the peripherals and it make many problems. reset_halt is not halt under reset but reset and halt on first address..
I tested successfull with on a F07_discovery :+1: f07_discovery> pystlink flash:erase:verify:gpio.bin DEVICE: ST-Link/V2-1 V2J35M26 SUPPLY: 3.26V CORE: CortexM0 MCU: STM32F070xB/STM32F071xB/STM32F072xB/STM32F078xB FLASH: 128KB SRAM: 16KB Loaded 13964 Bytes from gpio.bin file Erasing FLASH: [========================================] done in 0.18s Writing FLASH: [========================================] done in 0.41s Verify FLASH : [========================================] done in 0.09s
After flashing the F07_disco works as expected.
Can you be more verbose?
Regarding e72aca9: For pure flashing we can always cold-plug (connect under reset). Cold plug is also needed if the running program remaps the SWD pins or if the program sleep/stop/ etc for a long time. I only had flashing in mind. This needs to be rethought...

I see this with china programmer ST-Link V2
ou, I probably see that, from witch version ST-LINK API has STLINK_DEBUG_APIV2_WRITEMEM_16BIT functions?
If I remember right from V2.28. It took probably until V2.32 until things stabilized. In blackmagic I have following code: if ((Stlink.ver_stlink < 3 && Stlink.ver_jtag < 32) || (Stlink.ver_stlink == 3 && Stlink.ver_jtag < 3)) { DEBUG("Please update Firmware\n"); goto error_1; }
B.t.w. did you try the pc-stlinkv2 platform of the blackmagic debug probe with your clone?
Argh, I typed 21 instead of 32! Twice of by one on the keyboard. https://github.com/pavelrevak/pystlink/pull/18
Did the Stlink upgrade work for you? Did flashing work with the upgraded probe?
Yes, it was reported (I miss this info, I take some old STLINK device) now after upgrade it is working also with direct flashing! sorry this was my fault.. right now, only problem I see is reset_halt vs halt only on running firmware before flashing. is necessary to restart program and keep it halted before flashing.
The intention is following for flashing:
- unconditionally reset the device, so we catch devices with SWD remaped or deep sleeping (cold plug)
- Setup device to halt on reset
- release reset so we get halted
- Flash it
- remove halt on reset
- Pulse reset for a clean start of the device if -r is not given
For the other commands the CPU state is important. A hot plug (without reset) should done. I must admit, I did not care for this case.
Yes, Although in previous versions I don't have feature flashing under remapped SWD, the way was:
- bring device into hard reset (also it is working with jumper or hardwired button)
- sent command core_reset_halt
- release hard reset
- flash it
- SW reset to run program
points 1 and 3 we can omit if we don't have remapped SWD signals.
I did not think about state when is CPU in deep sleep, but I think it will work with same way.
or do you think about cases when SW reset is not enough ?
Personally on many devices I don't connect for programmer HW reset signal (only SWDIO, SWCLK), because SW restart is in all my cases enough.
