AM3874 EMAC boot

Other Parts Discussed in Thread: AM3874

Hi,

My customer is developing AM3874 system now.

Our customer is trying to boot up by EMAC boot. But customer's system does not execute the boot process . The symptom is the following.

AM3874 sends BOOTP request to host PC.

Host PC replys BOOTP to AM3874.

AM3874 sends BOOTP request to host PC again, not FTP request.

I attahced boot log and AM3874 received data list. Please see them.

Customer confirmed that AM3874 receives BOOTP reply from host PC in EMACMEM.txt. But Boot process does not forward to the FTP request. AM3874 repeats BOOTP request to host PC. Why?

Please let me know the cause of this symptom.

Quick reply is very helpful.

Best regards,

Hi Michi,

From AM3874 TRM, section 4.8.4.2 it seems that the BOOTP reply is not understood by the AM3874. Please tell your customer to check carefully if all the required data (per TRM section 4.8.4.2) is transmitted from the Host PC in the BOOTP response message. I'm sorry but I don't have the protocols here.

Best Regards

Biser

Dear Biser-san,

THank you for your advise.

I asked my customer regarding their reply message to AM3874. They say all messages that are needed by AM3874 are transmitted from Host PC to AM3874.

I attached the log file when the EMAC booting. Please see the attachef file.
