TMS320F28034: sw compatible 64pin with 80 pin

Hi,

Piero Yu said:

is it possible to burn 80 pin firmware to 64pin chip?

64-pin code would be compatible with 80-pin one but not the other way round. Again depends on your peripheral usage, for eg: 64-pin chip has only 12-ePWM channels and 14-ADC channels whereas 80-pin chip has 14-ePWM channels and  16-ADC channels.

the 80pin chip has GPIO13, but 64 pin has no. to avoid the interference from this pin,we have configure it to output low .
Now we will burn the 64bit chip with the GPIO13 program. Will there be any problem? Because we have considered the compatibility in our own design, the main concern is the chip has changed to 64pin.

Just worry about the register not in 64pin we set(such as GPIO13), will intefere the chip work normally.
Pls suggest.

Thanks, This resolved my issue
