TMS320VC33: TMS320VC33PGEA120 Issue

Herbert 

As noted on the product folder, there is no design support for this 27 year old device. I will see if I can get an answer for you, but I do not expect much success.

No update so far.

Why does the CS chip selection only affect the off-chip control and cause the on-chip memory of the DSP to be mistakenly modified?

Can you provide more detail on this?  for Chip Select, are you referring to  STRBx_B0 (byte-enable/chip-select signal)?   Which memory is being inadvertently being modified?

Even if the on-chip memory of the DSP is correct, is the calculation of CRC still wrong? 

CRC of what? how is this being calculated?

Has the software been check to ensure no rogue writes to the internal memory?
