Other Parts Discussed in Thread: TMS320F28069M, UNIFLASH
Hi,
We have designed a custom board based on TMS320F28069M MCU but we can't connect the emulator and program the board via JTAG. We have followed the design suggested by the datasheet as below:
But when we use UniFlash or CCS, we get this error:
We're using an external power supply to power up the board while the emulator is powered through the USB cable connected to the host machine. So I guess the problem is we don't have the common ground between the board and the emulator so the emulator doesn't see the ground on the TDIS pin so it assumes the target is not connected. Is my assumption correct? and if so, do you have any suggestion?
Thanks,
