I have a MCBSTM32 board with an ULINK-ME JTAG. Previously I used an evaluation version of MDK/µVision 4.01 and everything worked well. I installed the latest version (4.12), and when i tried download the code to the µC, µVision asked for firmware update. I clicked "yes", and after a few seconds µVision showed message "firmware update failed". I tried this several times after reconnecting the JTAG, but it's always fails. Is it possible to use the µVision 4.12 with my JTAG? Or where can i download the 4.01 version of µVision?
Maybe the USB stack or descriptors in the upgraded firmware has some bugs making it incompatible with your OS. So the firmware update doesn't fail - it just makes the ULINK-ME incompatible with your computer.
I resolved my problem. Before i write it down here i want to here the answer from Keil which i am still waiting for...
We are very curious - please tell us what you did!
OK, Keil support is still not answering. But i want to share my problem: Looks like my cable had a loose and shortcutted contact at my JTAG / SW connector. Before firmware flashing this was no problem. During the update this caused to a firmware update crash.
With the new replacment ULink-ME, this caused to an unstable connection.
So the problem is the small grey cable between target an ULink-Me. Seems to be very bugy.
