Hi, I am working on P1020 rdb for my project development. I am using QorIQ-SDK-V1.7 for software development. Earlier I erased my NOR Flash, so my VSC7385 firmware got erased from its location. When I flash my u-boot in the NOR, I get something like "No address specified for VSC7385 microcode. Phy not found", in my u-boot prompt. So I tried to flash my firmware "vsc2bin" into my NOR. I tried the following steps :


usb reset

fatload usb 0:1 0x10000000 vsc2bin

protect off 0xef000000 0xef03ffff

erase 0xef000000 0xef03ffff

cp.b 10000000 0xef000000 0x1ff8

protect on all


setenv vscfw_addr 0xef000000



Then I power cycle my board. Now I am getting this in my u-boot prompt :

uploading VSC7385 microcode from ef000000

Phy not found


To make sure the firmware is loaded OK, I tried this steps:

cp.b 0xef000000 40000 11000

go 40004


After doing this u-boot is getting stuck with following error:
