Problem of debugging TMS470 board using IAR J-link

Other Parts Discussed in Thread: TMS470R1B1M

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

Rui

'Memory access timed out @ 0040FFE0 -> JTAG speed too high?

    Everything is fine now after reconnecting the AWD directly to the ground!  :)

    Please be aware that the TMS470R1x series is not recommended for new designs.  Please see the full 'NRDN' notice here.

    Soon TI will be launching the new TMS470M series of microcontrollers.  This series will feature greater ARM CPU performance and a similar peripherial set to the TMS470R1 Series of microcontrollers.  Please come back soon for more information about the TMS470M Series of microcontrollers.  The product preview for the first two microcontrollers in the TMS470M series is available here: TMS470MF0660x - SPNS157. The TMS470M Series Technical Reference Manual is available here: TMS470M TRM.

    If you are just getting started with any of the TMS470R1X series of microcontrollers, I would highly recommend looking into using one of the TMS470M series of microcontrollers instead.
