Hi,
My customer has one issue for "Standard serial port boot" with C5402.
Customer's board works fine for "Serial EEPROM boot". But "Standard serial port boot" does not work now.
Customer would like to use "Standard serial port boot" for future memory expansion.
I already asked this issue to the below E2E thread.
https://e2e.ti.com/support/processors/f/791/t/770476
According to the customer information, the first bit of address bus is never changed when NG situation of "Standard serial port boot". So customer believe Parallel Boot sequence was passed, and the boot sequence is failed in next sequence (Initialize Serial Ports). Is this judgement correct?
Also, for Standard serial port boot, are some clock or input signals except for main clock needed?
Please advise me.
I appreciate quick reply.
Best regards
Michi
