I can not connect to STM32VLDISCOVERY after some experiments

Hi, Gordon, hi All!
After dodwnloading some code like A#.write(1); B#.write(1) etc. , I've checked that It works.
then I put reset(); command, and the board stoped and couldn't connect again. But trying to reload the board thru the ST-Link utility i see only "couldn't connect to target" and recomendation from this forum to download thru the "press and hold the reset button of the board and choose the Menu item "Target" -> "Connect" (or click on the connect icon). Release the reset button." doesn't work even after tens of attempts.. ouhhh, did I kill It ???

Update: I connected thru the terminal, and now the log looks like =undefined

echo(0);
=undefined
save();
=undefined

There were 246 errors!

Whath the errors? how can I reset the board?
Thanks!

I'm terrible sorry, for my previous topic, I just forgot to set jumpers CN3, responsible for swd programmer mode.
Sorry again.

I'm having problems saving using the same board.

I tried removing the CN3 jumpers but I still get the errors. How did you fix this?

Hi, I didn't. Try to use Ver1.44 https://espruino-nightly.noda.se/2013-12­-13/stm32vldiscovery/
but It didn't help me. I asked Gordon about It once again: http://forum.espruino.com/conversations/­334/#comment3774

Hi,

Looks like there is some issue with the save to flash functionality on the VL board - I'll try to take a look today but I'm really busy right now.

If anyone wants to take a look it might be that 'gen/platform_config.h' has the wrong details in it for where to flash the data (or maybe just what the page size is).

I don't know what I am doing but I will take a look and see if I can figure it out if you like.

I was trying to find platform_config.h for the VL but the only one I can find is in '/targets/arduino'.
'\gen' directory is empty.

Hi,

The platform_config.h file is auto-generated using: scripts/build_platform_config.py (so you'd have to modify that)

I could be pretty sure that's the problem as the flash page size is 2048, and I thought it was 1024 on those parts. I'll give it a try later...

Yes, that's what it was. I've just committed the changes, so if you wait until tomorrow, the espruino-nightly for STM32VL will support saving properly

Thanks for fixing so quickly. I did have a quick look but I'm too stupid to know what to do...

I picked up the latest nightly build from (https://espruino-nightly.noda.se/) this morning and I can confirm the changes made work and that there are no errors when saving programs on the STM32VL DISCOVERY board.

Great! Thanks for letting me know!

Dear StuntMonkeh, could you please help and repeat the code snippet from this topic with onInit function: http://forum.espruino.com/conversations/­334/#comment3836 thanks!
