When we revert to ae717b945de revision the command goes back to working, for some reason it doesn't work on master

This is the diff between those two versions: ae717b9...master. I think ae717b9...master#diff-df7217cd8a3907646570c002cf509f32R1439 this broke the flash loader which was introduced in PR #751. Ping @dhylands ?

dhylands · 2019-01-17T18:55:16Z

The latest master seems to be working for me. This is on an NUCLEO-L476RG. I was flashing Micropython which is split into 2 files due to the way the filesystem works.

    Update STM32F3xx chip ID that covers a few different devices. (#758)

My developement machine is ruinning ubuntu 18.10

michaelsobczak-qeexo · 2019-01-17T19:00:48Z

Thanks for looking into this. I'm also using L476RG to flash, i can try with latest changes and make sure I can reproduce. Mac OS X Mojave is our development environment

kmfarley11 · 2019-01-17T20:11:17Z

I can confirm the same behaviour on STM32F4 Discovery.
A flash attempt from master resulted in the same "flash loader run error", but reverting to ae717b9 worked for me.

Edit: Note that my OS was actually Linux Ubuntu 16.04 LTS. But the same behaviour and resolution as noted.

dhylands · 2019-01-17T20:54:55Z

I tried my F4 Discovery board and I was getting intermittent failures. For my first test I was using a201d3e which happens to be the system installed version of stlink (on my machine). Once I got the error mentioned above, mostly I got an unrecognized chip id unless I used --reset on the command line to st-flash.

When it failed, I had to power cycle the board to get it to work again.

My F4 had the V2J14S0 version of stlink. I updated it to V2J28S0 and I didn't get any further failures with the latest master or with version a201d3e

dhylands · 2019-01-17T21:02:02Z

For completeness, my NUCLEO-L476RG had stlink firmware V2J27M15. Since I had the stlink updater tool running I upgraded to the latest (V2J28M16) and the L476 continued to work with master and a201d3e

kmfarley11 · 2019-01-17T21:51:38Z

Interesting. My F4 discovery was at V2J25M14. So i got the latest (V2J32M22) from ST's website.

Even after updating my board with that, I still get the flash error when on master.
I did pinpoint that 7651d21 seems to be the first commit where I get the error though. All prior work fine (i.e. 358a913 worked).
for reference, my exact error from master:

kmfarley11 · 2019-01-17T21:54:40Z

Also to clarify, it happens every flash attempt and not intermittently.
It either works (pre 7651d21), or doesn't.
Looking at the code for that commit, not sure why it would be causing any issues. Just reporting observations.

michaelsobczak-qeexo · 2019-01-22T15:34:57Z

@kmfarley11 same experience, it has 100% failure rate when on the broken revision or later

dmitrystu · 2019-02-01T16:00:48Z

I have made some compatibility test for the st-flash 1.5.1-12-g30de1b3 (Linux) and some STM boars. Here is a result (32F103 and 32L433 is a bluepill-based boards)

Board	ST-LINK FW-VERION	SELF	STM32F103C8	STM32L433CC
NUCLEO-F303RE	V2J28M17	OK	OK	unknown chip id! 0x5fa0004
NUCLEO-L476RG	V2J32M22	flash loader run error	OK	Invalid flash type
STM32L100C-DISCO	V2J32S0	OK	OK	Invalid flash type

There is no problems when using STM32Cube Programmer software for any combination.

ashesman · 2019-02-06T21:33:51Z

I have the same issue. Upgraded to latest revision and can no longer flash. It seems to freeze at flashing the first block. It is OK on revision 3eab7b9 (1.4.0-49-g3eab7b9). Using custom hardware on ST-Link V2. Sorry I cannot provide any more useful debug information.

xor-gate · 2019-02-09T10:21:25Z

Dear all, I would like you to help out and skim through multiple revisions since latest release so we can pinpoint the exact PR which causes the problem.

v1.5.1...master

Git bisect could be used for finding the regression:

https://git-scm.com/docs/git-bisect
https://git-scm.com/docs/git-bisect-lk2009.html

Thanks all for the feedback, and sorry for the inconvenience latest master is broken. Never ever expect latest develop to work. Releases should 😃

dhylands · 2019-02-09T18:41:28Z

It was commit 7651d21 which caused the problem. The issue is that the chip ID for the F401 is 0x2ba01477 which appears to be the same as the CS32_CORE_ID and this causes the incorrect flash loader to be loaded onto the F4.

While looking into this I noticed that the code which prints which flash type was detected:
https://github.com/texane/stlink/blob/b9c315d990abfde3008a917e767c63d2c1c1ddf2/src/common.c#L1944
uses different logic from the code which actually does the flashing:
https://github.com/texane/stlink/blob/b9c315d990abfde3008a917e767c63d2c1c1ddf2/src/flash_loader.c#L253
so it says it's flashing an F4 but it loads the flash loader for the VL

rojer · 2019-02-11T14:35:33Z

@dhylands thank you very much! i don't know what this CS32 thing is but it breaks flashing of STM32F2.

VictorLamoine · 2019-02-11T16:18:14Z

Sorry about the trouble. What should be done to support both the CS32 and the STM32F2 / F401 if they share the same chip id but don't require the same flashing method?

rojer · 2019-02-11T21:31:06Z

@VictorLamoine i don't have the slightest idea. please revert the change to fix the regression, then figure it out.

VictorLamoine · 2019-02-12T07:40:37Z

You can revert the commit locally on your machine: git revert 7651d2116fd74c7803ea00ab1da7cf3d00faf44c.

I'm not a maintainer so I can't revert on the repository.

ag88 · 2019-02-12T18:04:50Z

i'd like to suggest that the manufacturer be made available as a command line option if possible.
i.e. the default would be stm32 and that to flash cs32 a manufacturer option would be necessary
the reasoning is that stm32 'clones' may detour from being 'fully compatible' with stm32 as things evolves

@ag88 totaly agree, the texane/stlink project aims to support ST Microelectronics products and to be compatible with clones without breaking existing things. The problem with clones on the same IDs with different flash handling etcetera involves a lot of hacking. Also the current implementation is also not very clean (compared to flexible OpenOCD tcl scripts). There are a lot of conditional checks all around the flash loader code for different scenarios which could be simplified (eg look at pystlink)

Hi all,

I have reverted the CS32 commit. Could you verify it works again?

Kind regards,
Jerry

@xor-gate works for me now on the latest master. Thank you everyone for the help!

@michaelsobczak-qeexo thanks for verify! Sorry for the long delays and inconvenience.
