Hi guys
I use IAR J link to program my TMS470 board, however, there are always following errors when debugging . Anyone can tell me what might be the reason resulting those errors and how can i solve them? Thanks a lot


Errors:

'Memory access timed out @ 0040FFE0 -> JTAG speed too high?
Unexpected CPU core mode : 13 (Expected 0x17, CPSR=000000D3), ReadMem: Words @ Addr 0x5F0'

Thanks for your reply, Alex

Actually the EVB (TMS470 kickstart kit ) works well with the exactly the same setting, but not with my board, which has the same controller as EVB. Here is the code of macro file:

Thanks for your reply, Alex



I've checked the datasheet of the controller and the schematics of TMS470R1AXX EVB to compare with mine. It seems that everything is correct. Besides, power supply is ok too. Is it possible for you to tell me what might be the problems when those errors show up? I can further check my board if i have a direction. Perhaps the chip is broken, as the memory can not be read? Thanks in advance.

Thanks for your reply, darkleo

However, it still doesnt work after i change the numbers. Can anyone help me??

Finally solve the problem . The watchdog should be directly connect to the ground other than pull down to the ground by resistor. Thanks for all your advice. Have a nice weekend !
