STM32F103 BootLoader Go command

Hello, I'm using STM32F103, have a problem to start go RAM downloaded code.

Connect by serial. Read memory, Download, all other commands to BootLoader work OK - reply as explained in AN2606. After 'go' command, it doesn't look it starts. I try to download easiest code (40 bytes) which should change memory, so I could then see the result, but nothing happens. 'Go' command returns ACK 2 times, after command itself, and after address. BootLoader v 2.0. [ This message was edited by: YuSh on 13-01-2009 19:31 ]

Hi, Johan,

could you tell me what is the code you succeded to start from RAM, by BL 'GO' command ? Till now, I had no code, even easiest, gives sign of starting to run. If you have some code do start, it may help to understand the problem. With regards, Yuri.

I can just say that I've had the same problems. However, for me it works for some applications but not for others.

The applications that I can't start from the bootloader, works if I reset the device and boot from flash instead... Is this a documented bug, or are we doing something wrong?
