Technical discussions about the TI C3x DSPs (including the C31, C32 and C33 DSPs).
We have a situation on one of our legacy design of 320C31 DSP. Reset pin of C31 is connecting to Maxim Power on Reset chip (MAX708). At power up, There is a clock coming in to X2_CLK of C31, but there is no divided by two H1 nor H3 clocks coming out. If we force external Master Reset to MAX708, to create C31 reset after power up, H1 clock will come out. Once the H1 clocks coming out, we are able to erase flash, programming it, and upload FPGA firmware through emulator port. We never able to see this anomaly again after programming the flash and upload FPGA firmware. I like to know what are possible causes of this failure. I am greatly appriciated.
