Problems getting sd-link to flash - STM32746G-DISCO_Demo_V1.1.0.hex

I'm having problems getting sd-link to flash. I've no tried it on linux, a mac, and a Raspberry Pi. The Raspberry Pi at least manages to read it!

I'd just like to flash the demo S

TM32746G-DISCO_Demo_V1.1.0.hex correctly - once that works, I'm hoping flashing embedded code will be easy!

What am I doing wrong?I've got the link up:

st-util

I get these errors from st-info:

st-info --chipid

Which doesn't look good.I seem to be able to read from flash memory, but not write to it:

I assume you mean ''no

w

tried it ...'' - would have a significant influence on the meaning.> I've no tried it on linux, a mac, and a Raspberry Pi. The Raspberry Pi at least manages to read it! Assuming you are running a Linux OS on the Raspberry, it should work on a ''normal'' Linux, too. Perhaps just an issue of missing user permissions ? Using Crossworks on Linux (supports the ST-Link), I need to add rule files to /etc/udev/rules.d, to allow others than root access to such USB devices.

BTW, forgot to mention that the ST-Link V2.1 has another product ID than the older V2.

So earlier/older udev permission rules do not apply to this new version ...

Yes, 'now tried it' - you're right.

I've got the rules set to mode 0666 - so that shouldn't be the problem.This is what puzzles me:

st-flash read out.bin 0x8000000 1048576

It is happy to read - but, suddenly, can't write.

Honestly, I don't know. Haven't tried the st-link tools since the (in-)famous vl-discovery times. I always used the boards from within Crossworks. Perhaps it's an issue with the tool itself, and the new V2.1 hardware ? Wine/Windows as last resort ?

Hi brooks.peter.001,

Try to upgrade the ST-Link firmware to V2-1 version through this Link

http://www.st.com/content/st_com/en/products/embedded-software/development-tool-software/stsw-link009.html

through the ST-Link utility. -Hannibal-

That requires Windows - and you could flash you application directly from the ST-Link utility then.
