I made a test board according the mpc8306som, now , I want to program the flash(M29W640GT70NA), but find the CodeWarrior 8.8 flash programmer hasn't M29W640GT device,only has M29W640DB. Using M29W640DB device ,the flash erasing doesn't work,the error message is "can't get correct device ID", and the LCS0 doesn't have any active waveform. the hardware around LCS0 i believe is correct,because the LCS0 has active waveform in power on flow .
How to handle this problem?
Any suggestion is helpful, thanks!
