Hello, I am using Keil uvision 4 (arm-mdk453 package) for STM32VL discovery board. It used to be working properly, but now I'm having a problem when I try to download to flash or to debug. I receive popup messages like ''Internal command error'', ''Flash download failed: target dll has been cancelled''. I did upgrade to (mdk454 package) but still have the same problem. Any help will be highly appreciated.
Best Regards,
Hello Zied,
If getting an "Internal command error" with a ST-Link, with MDK-ARM v4.54 (an older version of the Keil tools), some suggestions:- Is "Download to Flash" checked? http://www.keil.com/support/docs/3666.htm- If a previous program running on the board is locking up: www.keil.com/.../3662.htm- The firmware on the STLink is too new for this older version of the Keil tools. Temporarily downgrade the STLink Firmware:www.keil.com/.../3774.htm
