STM32VL won't flash #579

Hello,

I'm getting following error on stm32vl discovery board.

Thats weird, i'm not sure what causes the problem as the flash loader is written to RAM and then fails at the end.

Faduf · 2018-04-01T09:42:28Z

Have you tried with the Boot0 to Vdd before powering the board. This solved the problem for me.

Nightwalker-87 · 2020-02-21T22:35:31Z

Please verify if the problem still exists in Release v1.6.0 and/or if the feedback by @Faduf resolves the issue.

nerdmaennchen · 2020-03-14T11:52:10Z

Just got fresh hardware to play with (AZDelivery STM32 STM32F103C8T6 and a Youmile ST-LINK V2 Emulator) and see exactly this behavior when flashing via st-util as gdb server and arm-none-eabi-gdb as client.

I can flash the target with st-flash without any problem. It seems to be an issue specific to st-util.

How can I help?

nerdmaennchen · 2020-03-14T12:02:26Z

i got some more output from st-util with -v99:

The problem might be that the core is not runningt when flashing the second sector; I'm just guessing here

nerdmaennchen · 2020-03-14T12:13:01Z

before you ask: I'm currently using the master's HEAD (f5d0454)

Nightwalker-87 · 2020-03-14T12:16:47Z

@nerdmaennchen: Thanks for the feedback. What is the core ID of your STM32F103C8T6? Can you verify that it is not a CKS32F103C8T6 with a fake marking? We currently face several problems with this sort of chinese clone boards (see Release v1.6.1 Tickets) that appeared on the market from Dec 2019. I would like to rule out that we accidentally mix up different issues. Therefore it would be helpful to either be sure of original ST-Microelectronics chips or have another type of board used to analyse this problem, which is not affected by this product counterfeiting.

nerdmaennchen · 2020-03-14T12:18:50Z

the reported coreid of the target is in the above log:

2020-03-14T12:57:10 DEBUG common.c: core_id = 0x1ba01477

frankly, I don't know if it's genuine or not (it was very cheap though)

Nightwalker-87 · 2020-03-14T12:30:10Z

Looks as if you are lucky, though you caught a cheap board. The affected boards mentioned have Core ID 0x2ba01477, so we should be fine then. Thanks for verifying. 👍 We will keep up with this then, please give us some time to solve this. Of course you may take a closer look as well, if you wish to do so.

nerdmaennchen · 2020-03-14T12:38:55Z

Of course, take the time you need!
Also I'd like to express my appreciation for your project:

Kudos! I've been using your tools since five years or so and they are sill my go-to-tools
You rock!

If you need any help, I'd be delighted to do my part.

Nightwalker-87 · 2020-03-14T14:43:57Z

It appears that we need a closer look at what happens step by step when flash_loader.c is called to further encircle the issue. @slyshykO: Are you interested to look at this on your Windows system? As I only have a non-genuine CKS32F103C8T6 chip I may only look into the code, but without the ability to test and debug properly. :-/ Any help and ideas are greatly appreciated.

nerdmaennchen · 2020-03-15T08:39:16Z

For some reason the PER bit is set when writing the first word to the second page.
The code that performs page erases before programming seems is executed and is written exactly as stated in the Programming Manual (PM0075).

However, if I do a mass erase (with st-flash) before programming the device via st-util and gdb everything works smoothly.

nerdmaennchen · 2020-03-15T10:27:47Z

found the problem.
the PG bit might be set before doing the page erase.
when the START bit is set later the PG as well as the PER bits will be set and the flash controller will remain in the PG state and not do a page erase at all.
That explains why the first page was programmable but the second wasn't, since the flash loader set the PG bit during programming of the first page.

cheers

Nightwalker-87 · 2020-03-15T12:15:58Z

@nerdmaennchen: Thank you so much for your contribution. I'll review the PR as soon as possible. You are on linux? Can someone else test this with another board (and eventally a different OS) as well - ticket was opened for macOS BTW) to have redundant verification? @bmarvo, @bolorkhuu or @Faduf maybe?

nerdmaennchen · 2020-03-15T12:19:30Z

jep, im an Arch-fanboy (Linux) and I don't have easy acess to other OSes.

However, IMHO the fix is entirely OS independent as was the cause for the problem.

Nightwalker-87 · 2020-03-15T12:25:36Z

That's what I thought as well, but I feel like that it is always good to have verification on at least a second setup. Don't bother about this too much, you are fine and I believe you spent enough valuable efforts on this. Let somebody else take a look at it and relax. ;-)

nerdmaennchen · 2020-03-15T12:27:27Z

very well then.

don't worry about my time. I actually enjoyed it quite a lot :D
