[STM32U5x5]: Last bytes are not written (flashed) when len(<binary>)%16 <= 8 #1303

victor-dryad · 2023-04-15T08:23:38Z

Actually, a blind workaround for the issue is simple:

if len(<binary>)%16 <= 8
   then pad 8 bytes to the end of the binary

Programmer/board type: [STLINK/V3]
Operating system an version: [Linux]
stlink tools version and/or git commit hash: [1.7.0-261-g1745bf5-dirty]
stlink commandline tool name: [st-flash]
Target chip (and board, if applicable): [chip ID 482]

Full --debug printout is about 35Mb, if it is needed - just tell me the best way to share them (failed and successful ones)

However during verification these last bytes are not found in the memory.
(This fact also checked and confirmed using official STM flasher)

(I have edited a little the code of debug printout, so do not be surprised)

You can see, that last 8 bytes are 8FF instead of 400 and 4*77
FF - these were written during erase step and were not replaced during binary flash.

The text was updated successfully, but these errors were encountered:

@victor-dryad I do have this board available for testing. Can you provide your binary somewhere (temporary webspace) for testing on a second instance? You can paste your logs here https://pastebin.com/ (perpetual distribution is not necessary).

Simply add/remove zeros in the end of it. Now it has exactly 8 bytes in the end

@victor-dryad Would you propose a fix based on your idea and the relevant code part?

@victor-dryad Would you propose a fix based on your idea and the relevant code part?

You are the driver. If you see it logical from point of view of the code, why not? I cannot estimate the code because it is full of details I have no knowledge.
For the users it's more important to get the tool running without problems.

Nightwalker-87 · 2023-05-22T18:41:18Z

@victor-dryad My knowledge to the implementation is limited here as well, because I'm not the author of the code, nor have I gained the complete overview of original implementation - to be honest nobody has, as several people contributed with different attempts to implement certain functionalities. I have stepped in as a maintainer and try to resolve bugs and find my way through the source code, just as many others. 😉

@victor-dryad My knowledge to the implementation is limited here as well, because I'm not the author of the code, nor have I gained the complete overview of original implementation - to be honest nobody has, as several people contributed with different attempts to implement certain functionalities. I have stepped in as a maintainer and try to resolve bugs and find my way through the source code, just as many others. wink

Ok.
then I'll try to look in during coming (long) weekend

victor-dryad · 2023-05-28T08:23:22Z

I had a look before weekend to be able to play with the h/w.
An opinion:
The corrections have to be placed in flash_loader.c:
The main write loop is from line

    for (off = 0; off < len; off += sizeof(uint32_t)) {
      uint32_t data;
............... (print is skipped)............
      write_uint32((unsigned char *)&data, *(uint32_t *)(base + off));
      stlink_write_debug32(sl, addr + (uint32_t)off, data);
      wait_flash_busy(sl); // wait for 'busy' bit in FLASH_SR to clear
    }

(a purpose of uint32_t data is not clear for me)
Next "if" looks like a workaround for an issue similar to the discussed here one.
I would propose after it to put a piece of code as proposed in the issue report:
if ((flash_type == STM32_FLASH_TYPE_L5_U5) and (len % 16 <= 8)) { ..... write zero two times. (one write operation writes 4 bytes, as I understood) }
I added in "if" STM32_FLASH_TYPE_L5_U5 check because the issue is not confirmed for other flash types in the group.

@victor-dryad As I read it uint32_t data needs to be defined to serve write_uint32(...) and stlink_write_debug32(...) within the for-loop. Do the proposed lines (written out state) solve the issue? We should give it a try and then analyse the derived result.

Ant-ON · 2023-05-29T03:28:37Z

@victor-dryad This code has an error related to array dereferencing (the base variable may not be aligned to 4 byte). But it should not affect full data writing, if the code is executed without segmentation errors. The code should simply write "noise" into the last bytes of the word.

I would rewrite line

write_uint32((unsigned char *)&data, *(uint32_t *)(base + off));

to

data = 0;
memcpy(&data, base + off, (len - off) < 4 ? (len - off) : 4);

victor-dryad · 2023-05-31T11:18:57Z

@Nightwalker-87
Because I am quite pure in C, the proposed attempts above where failing with "ERROR common_flash.c: Invalid flash address".
However this works:
common_flash.c stlink_write_flash after first "if":
L1436+


  if ((len % 16 <= 8) & (sl->flash_type == STM32_FLASH_TYPE_L5_U5))
  {
    len += 8;
  }

L1167 change makes the printout shorter:
    fprintf(stdout, "-> Flash page at %#x erased (size: %#x)\r", addr, page_size);

Tested successfully with len%16 = 1..8 (file size 0xba061..0xba068)

One more question comes to my mind:
The issue operates by absolute value - 8.
May it be possible that the value has relation to sizeof(uint32_t)?
If not - just make the changes in code.

Nightwalker-87 · 2023-06-07T21:28:13Z

@victor-dryad Thanks. I'll test this on my Nucleo-U575ZI-Q as well.
I still need to think about your additional comment.

Nightwalker-87 · 2023-06-08T10:47:27Z

@Ant-ON I've included your proposal into my working copy for testing.
Looking at flash_loader.c and common_flash.c from a more general perspective leaves me uncertain, whether there is further potential for refactoring work related to this topic. It would be preferable to have functions and routines that are generalised and applicable to most chipsets in order to avoid individual approaches where possible. I'd also prefer an improved structuring along with further inline documentation. Any ideas?

victor-dryad · 2023-06-08T17:05:56Z

@Ant-ON with further inline documentation. Any ideas?

Minimal improvement:
Put issue number as comment in the code

//issue num start
...
//issue num finish

:-D

Nightwalker-87 · 2023-06-08T18:05:36Z

@victor-dryad As to our common practise this will be listed in CHANGELOG.md and the Release Notes as soon as this issue is finally resolved and verified. Also there will be a reference in the commit which will close this issue.

I know it is a kind of a struggle to gain an overview of the available functions, but I'll try to do my very best to improve and unify the appearance. Thus for the first (even though off topic) I'll make sure that all existing functions are correctly declared in the related header files. Then I'll check the header includes and do the testing with the provided binary, to which I've added a few zeros at the end. Otherwise I can not rule out any strange side effects during compilation. 😕

victor-dryad · 2023-06-09T07:16:51Z

I've just mentioned a topic "inline documentation". Definitely, changelog and release notes are out of this topic.
List of functions and related to it descriptions - it is another story. I am not ready to discuss it. Except of very general (spherical chicken in vacuum) - "any project has to have requirements specification", something similar to " it is better to be healthy, but rich".

Nightwalker-87 · 2023-06-09T09:19:58Z

@victor-dryad You may have a look at the testing branch (may be instable!). It is an approach to start off with the mentioned restructuring issue for the library (stlink-lib). You may test it with your board and give some feedback in the meanwhile. We also need some testing on Windows later on to verify that all common functionality is preserved.

Nightwalker-87 · 2023-06-09T12:46:18Z

With the change from @Ant-ON, we can skip the following:

if ((len % 16 <= 8) & (sl->flash_type == STM32_FLASH_TYPE_L5_U5))
{
len += 8;
}

I have tested the changes successfully with my Nucleo-U575ZI-Q using the testing branch and thus can verify that this solution is working.

However I'd prefer to have someone checking the other refactoring which has taken place to verify that we do not accidentally introduce any errors. As mentioned before, we should run it on Windows as well.

(Closes #1303)

Nightwalker-87 · 2023-06-12T10:01:20Z

Tested native MinGW building on windows (Windows 10), board detection and basic toolset commands in the meanwhile.
So far everything looks fine and we can merge testing into develop, which will close this issue by automation.
