Burning Linux uImage into i.MX53 QSB

[brahman_river]

Now I'm trying to burn Linux uImage I built into i.MX53 QSB. After executing tftpboot, however, any key input is not accepted.

-------------------------------------------------------------------

MX53-LOCO U-Boot > tftpboot 0x00020000 uImage FEC: enable RMII gasket PHY indentify @ 0x0 = 0x0007c0f1 Using FEC0 device TFTP from server 172.16.1.15; our IP address is 172.16.15.45 Filename 'uImage'. Load address: 0x20000 Loading: FEC: Link is down 7809

I'm not sure if the file transfer was sucessfully completed. It seems weird that the left side of RJ-45 LED was blinking all the way. 

I also tried to loadb command to send the image via serial I/F, but it didn't also make progress after just 2 bytes were transferred.

Can environment variable have something to do with this failure? I attach an file showing all the variables. Does anyone have an idea?

Best Regards,

Hi, 

As long as I see the sniffer log, Just a block of data is sent from TFTP server after i.MX53 QSB send Read Request, and no more data is transferred.

If I were you, I'd run wireshark on the server.
