I can't manage to flash one of these: https://www.ebay.com/itm/Mini-System-Development-Board-ARM-STM32-F030F4P6-CORTEX-M0-Core-32bit-48-MHz/331978736223?hash=item4d4b79825f:g:NncAAOSw-09aQKDm

It seems to --probe correctly, erase correctly, the stlink led flashes, but it does not flash the actual firmware, i tried to flash the same firmware with the same setup on an stm32f103c8t6 and it worked.
I'm using a cheap chinese stlink clone.

Output with --debug:

Ok the issue was that the chip had the usual write protection enabled, I had to use a serial adapter and execute this other tool

stm32flash -k /dev/ttyUSB0

To unlock it.

So, maybe, this issue can be changed to "make st-flash give an appropriate warning on what's happening" because this was rather counter intuitive

xor-gate · 2018-04-06T08:46:23Z

There are multiple issues closed and related to write protected microcontrollers which can be unprotected by mass erase and then flash. Not sure how we can detect this but it is a serious usability problem of the tools.

my stm32f103

enable sw is ok

now stm32CubeMX Create project this value default Disabled

Just my two cents: had the same situation, only for STM32F1. Managed to disable write protection using STLinkV2 (which is integrated in STM32F1DISCOVERY board) via OpenOCD command:

$ openocd -f interface/stlink-v2.cfg \
          -f target/stm32f1x.cfg \
          -c "init; reset halt; stm32f1x unlock 0; reset halt; exit"

where target is your CPU or board.

@joe-skb7 I get the same error as @hggq for my STM21L171 device. How do I disable write protection using openocd?

joe-skb7 · 2019-02-07T09:05:59Z

@nit1995 See my post above.

HI,
can you please guide me how can we achive level 2 protection through openocd

joe-skb7 · 2020-06-21T16:10:45Z

@kahanchudasama Locking with OpenOCD can be done as shown here (in Flash Driver: stm32f1x section, see lock command). Something like this should work (if you use STLinkv2 programmer and your chip is STM32F1xx):

$ openocd -f interface/stlink-v2.cfg \
          -f target/stm32f1x.cfg \
          -c "init; reset halt; stm32f1x lock 0; reset halt; exit"

Whether it's level 2 or no -- can't say for sure, but documentation for lock command says:

Locks the entire stm32 device against reading.

I think it's better to read STM32 corresponding registers and check how exactly it was locked, after performing mentioned OpenOCD lock command. Either that, or check how that OpenOCD commands is implemented.

As @xor-gate mentioned this is a serious usability problem.
Can somebody propose a PR to finally fix this in the toolset?

Nightwalker-87 · 2021-04-04T16:57:33Z

IMHO documentation should be improved here.
Can one think of a reasonable way to remove write protection via the toolset directly?

Ant-ON · 2021-04-05T04:13:21Z

@Nightwalker-87 Yes it possible through writing of protection bits (part of option bytes).
I added check WRPERR error to the /~https://github.com/Ant-ON/stlink/tree/fl_fix branch. In the event of a write error due to the set protection bits, a corresponding message should be displayed.
