AM6442: TFTP Ethernet Uboot

Jonas Frewert

Part Number: AM6442

Hello,

I was trying to boot Linux from Ethernet via TFTP but was frontend with the following error: TFTP error: trying to overwrite reserved memory...
I copied the tiboot3.bin from the SD card that came along with the board.

These were the steps I have taken:

=> setenv ipaddr 192.168.1.102 (EVM Board)
=> setenv serverip 192.168.1.101 (TFTP Server Host machine)
=> printenv kernel_addr_r ramdisk_addr_r fdt_addr_r
kernel_addr_r=0x82000000
ramdisk_addr_r=0x88080000
fdt_addr_r=0x88000000
=> tftpboot 0x82000000 tiboot3.bin
link up on port 1, speed 100, full duplex
Using ethernet@8000000 device
TFTP from server 192.168.1.101; our IP address is 192.168.1.102
Filename 'tiboot3.bin'.

TFTP error: trying to overwrite reserved memory...
=> TFTP error: trying to overwrite reserved memory...<INTERRUPT>

Anybody has an Idea what I am doing wrong?

Regards,
Jonas

Hi Jonas,

Why do you want to download tiboot3.bin?

Once you have U-Boot prompt now, U-Boot is already in execution, the next file you need to download is kernel Image and board drb.

Hi Bin,

thanks for the quick response. Oh well, I thought this was the kernel image, my bad.
I have the following (screenshot) 4 files on the sd card and I thought the u-boot disc image file would have been the u-boot image. Where can I get the kernel image from?

Hi Jonas,

The kernel image is in the boot/ folder in the second partition of the SD Card.

By the way, please review the following document, it may help you understand the Linux boot flow on AM64x and what these boot images are.
