I am interested in possibility of debugging an ACTEL MP7 (ARM7TDMI-S soft core) by KEIL ULINK (I have got an ULINK version 1 ). I use the GENERIC ARM7 Little Endian settings because there is not direct support for a MP7 core in the the KEIL uVision3. The ULINK did find an ID of my MP7 core, but in an effort to debug the MP7 either in RAM or FLASH, the uVision gives me the message: Could not stop the ARM device. Check the JTAG cable. I try to decrease CLK of ULINK, but I received the same error. Where the problem could be? The code was compiled in the uVision and downloaded into device via an ACTEL interface with full functionality of it. Question: Is it anywise possible to debug the ACTEL's MP7 core with the ULINK in the Keil uVision3? Thank you. Michal
