Hi guys, My controller(TMS470) works well when i debug it, but it stops after i disconnect the debugger(J link) and the consumed current is much lower too . Does anyone know how to solve this problem? Someone suggested me to change debug mode to release mode, but nothing happened after changing. Thanks a lot Rui

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 !

Quote from darkleo: “Hi Your problem in this line __readMemory32(0x0040ffe0, "Memory"); __readMemory32(0x0040ffe4, "Memory"); __readMemory32(0x0040ffe8, "Memory"); __readMemory32(0x0040ffec, "Memory"); change this symblos "4" on "0" and you'll get full access to memory and flash” Thanks for your reply, darkleo However, it still doesnt work after i change the numbers. Can anyone help me??

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. Rui

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: SetupRAM() { __message "Executing memory setup macro B1M RAM\n"; //__emulatorStatusCheckOnRead(1); __emulatorStatusCheckOnRead(0); // Disable reset at illegal address and access violation to // avoid resetting the CPU when debugging. __writeMemory32(0x00004007, 0xffffffe0, "Memory"); // SYSE…

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?
