@victor-dryad : Just for a better understanding: What happens, if you change } while (addr < (base_addr + size)); to } while (addr <= (base_addr + size)); in common_flash.c line 1170?

Unfortunately looks no improvement.
Anything to add to improve the debug logging?

However one more thing fixed:

when I run st-flash let say - from scratch, I receive the fault on erase of first page (see log bellow)
when I flash using official tool, and then repeat it with st-flash - I receive the fault on erase of second page (as was reported)
it is the same with/without the correction in common_flash.c line 1170

The trials made under Ubuntu Mint 21.1
Actually, a final goal of me is to to use st-flash on a RaspPI. Later I will try the flashing there.
Therefor a suggestion:

Include in (debug) printout an info about OS version. And maybe any addition info about USB might be helpful?

Actually, the OS info in detail is not too important, apart from the system type (windows, linux) because behaviour within different flavours of debian based distributions is usually very similar, if not the same. Also we do test the toolset on debian based systems regularly. More detailed USB debug info appears not to be trivial to implement from my point of view. Here we mostly rely on the external libusb library.

I'll check the log above in more detail soon.
For now I recommend to rollback the suggested change and recompile, in order to preserve the original state for further review.

@victor-dryad Flash programming error: 0x00000080 is mean FLASH_SR = 0x00000080. Bits are set in the error:
Bit 6 SIZERR: Size error
Bit 4 WRPERR: Write protection error

Perhaps is write protection set?

Kind of blind research:
common_flash.c stlink_erase_flash_page, second else-if branch for STM32_FLASH_TYPE_WB_WL.
from line 1096 the code is replaced with additional logging and one hack:

      uint32_t flash_page =
          ((flashaddr - STM32_FLASH_BASE) / (uint32_t)(sl->flash_pgsz));
      stlink_read_debug32(sl, FLASH_WB_CR, &val);

      ILOG("\n\nstlink_erase_flash_page: \n");
      ILOG("stlink_read_debug32(sl, FLASH_WB_CR, &val) val=%#x\n", val);

      val &= ~(0xFF << 3); // Clear previously set page number (if any)
      val |= ((flash_page & 0xFF) << 3);
      uint32_t val1 = val;
      val = 0x40000002;

      ILOG("flash_page(%#x)=(flashaddr (%#x) - STM32_FLASH_BASE (%#x)) / (uint32_t)(sl->flash_pgsz) (%#x)\n",
           (flashaddr - STM32_FLASH_BASE) / (uint32_t)(sl->flash_pgsz), flashaddr, STM32_FLASH_BASE, (uint32_t)(sl->flash_pgsz));

      // sec 3.10.5 - PNB[7:0] is offset by 3.
      val &= ~(0xFF << 3); // Clear previously set page number (if any)

      ILOG("val(%#x) &= ~(0xFF << 3)\n", val);

      val |= ((flash_page & 0xFF) << 3);

      ILOG("val(%#x) |= ((flash_page & 0xFF) << 3)\n", val);

      ILOG("stlink_write_debug32(sl, FLASH_WB_CR (%#x), val(%#x instead of %#x))\n\n", FLASH_WB_CR, val, val1);

      stlink_write_debug32(sl, FLASH_WB_CR, val);

This hack solves the issue in my case.
The hack:
I set a value which was read first time, then a new value (read on next steps) is ignored.

@victor-dryad When looking at the if-clause in L1071 in common_flash.c (current testing branch), we find a (very) similar procedure for STM32_FLASH_TYPE_G0, STM32_FLASH_TYPE_G4, STM32_FLASH_TYPE_WB_WL. Thus I assume all related boards should be affected respectively.

Talking about testing branch:
here is the else-if peace of code I mentioned:

stlink/src/stlink-lib/common_flash.c

Line 1105 in fc99064

} else if (sl->flash_type == STM32_FLASH_TYPE_WB_WL) {

As far as I can see,
the code for another boards differ.

Nightwalker-87 · 2023-06-09T14:45:26Z

Well, they are similar - only the HEX-values differ.

victor-dryad · 2023-06-09T15:09:58Z

Well, they are similar - only the HEX-values differ.

A way to create a mask is (may be almost) the same. the values differ.
Where can I read about these registers and meaning of bits to set/clear?

Nightwalker-87 · 2023-06-09T22:19:29Z

... the respective reference manuals? I'd try the one for the ST32WLE device you have at hand (section 3.10.5) and then extend research to STM32G491 or any G0 device (section 3.7.5), taking into account related sections of interest.

Nightwalker-87 · 2023-06-19T22:23:05Z

@victor-dryad I still don't see the point that is actually leading to this. 😞
We apparently have a workaround, yes, but it's not what I'd add to the code, if we don't understand this behaviour...
@Ant-ON Any idea?

Nightwalker-87 · 2023-06-24T22:20:11Z

We need more contributors here with similar hardware for further investigation and testing.

Nightwalker-87 · 2023-06-28T20:32:03Z

@victor-dryad You may give it another try with the latest testing branch and without any custom patches from your side, though there were no specific fixes for this problem. However it may be useful to generate another output with a recent commit to see if there are any effects regarding the received output. Please make sure to run
sudo make uninstall && sudo make clean && sudo make install
to ensure a proper clean-up before additional testing.
It would be great, if the output could go to pastebin.com.

--> This is wrong: The WLE does not have a dual bank flash (per data sheet) and thus the related code necessary is not implemented. This option needs to be disabled in /config/chips/WLEx.chip, but I'm unsure yet, if it has an effect on this issue.

The data between 0x0800 0000 and 0x0800 0800 did get ereased succesfully. The data in other memory regions wasn't erased.

I've tried removing the dualbank flag in /config/chips/WLEx.chip as suggested by @Nightwalker-87 , but this didn't change anything.

Unfortunately I'm not capable to help debug this issue, but I'm more than happy to test or try any suggestions on the hardware that I have.

@victor-dryad I believe to have found a bug in common_flash.c L99ff.
The following block is obviously misplaced and belongs to the respective case for the H7 addressed earlier:

    if (sl->chip_flags & CHIP_F_HAS_DUAL_BANK) {
      cr2_reg = FLASH_H7_CR2;
    }
    cr_lock_shift = FLASH_H7_CR_LOCK;
    cr_mask = ~(1u << FLASH_H7_CR_SER)

Commit 7dcb130 fixes the obvious bug above.
Apart from this we are not able to verify or further investigate due to missing feedback and contribution.
Against this background I am closing this ticket now as resolved.
Please open a new ticket should the problem persist.
