I can program the stmf32f334 chip without problem with the desktop version ''FlashLoaderDemo.2.7.0'' - it is Ok.

But the command line version gives error:

''The instruction of ''0x7c911699'' referenced memory of ''0x00000000''. The memory could not be ''read''.''

I checked with the scope. The bootloader dialog starts Ok. PC sends 0x7F, receives 0x79.

My boot.bat file is below:

''c:\Program files\STMicroelectronics\Software\Flash Loader Demo\STMFlashLoader.exe'' ^

-c --pn 6 --br 9600 --co ON -Rts --Hi -Dtr --Hi -Dtr --Lo -i STM32F3_34_03_64K ^

-e --all -d --fn .\Release\F334_nucleo_HRTIM.hex ^

-Rts --Lo -Dtr --Hi -Dtr --Lo

I try to change the baudrate, no difference.

The chip name STM32F3_34_03_64K is correct. The desctop version shows

it.

Great thanks for help,

Varuzhan

Sounds like a Windows error, the source is supplied review/debug.

any person, who know the problem.

I wouldn't put too much hope in an answer from ST here...

''The instruction of ''0x7c911699'' referenced memory of ''0x00000000''. The memory could not be ''read''.''

That sounds like an ''evil'' NULL pointer reference, probably because of a un-checked return value from some resource allocation function (just a guess). ST might not have tested it on all relevant versions of Windows (including 32/64-bit variants !).
