DM8148 EVM setup script u-boot parameters not working
I just installed ti-ezsdk_dm814x-evm_5_03_01_15 and ran the setup script. It eventually says:
Resulting u-boot variable settings:setenv bootdelay 4setenv baudrate 115200setenv bootargs console=ttyO0,115200n8 rootwait rw mem=256M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M ti814xfb.vram=0:16M,1:16M,2:6M root=/dev/nfs nfsroot=192.168.0.136:/srv/dm814x-evm/filesystem ip=dhcpsetenv bootcmd 'colorbar;dhcp;setenv serverip 192.168.0.136;tftpboot;bootm'setenv autoload nosetenv serverip 192.168.0.136setenv bootfile uImage-dm814x-evm.bin
When I use those parameters in u-boot I get the following:
Net: <ethaddr> not set. Reading from E-fuseDetected MACID:40:5f:c2:40:97:eccpswHit any key to stop autoboot: 0 Unknown command 'colorbar' - try 'help'link up on port 0, speed 1000, full duplexBOOTP broadcast 1DHCP client bound to address 192.168.0.122link up on port 0, speed 1000, full duplexUsing cpsw deviceTFTP from server 192.168.0.136; our IP address is 192.168.0.122Filename 'pxelinux.0'.Load address: 0x81000000Loading: T TFTP error: 'File not found' (1)Not retrying...Wrong Image Format for bootm commandERROR: can't get kernel image!TI8148_EVM#
It would appear that calling 'dhcp' changes the bootfile from uImage-dm814x-evm.bin to pxelinux.0
setting bootcmd to 'dhcp;setenv bootfile uImage-dm814x-evm.bin;setenv serverip 192.168.0.136;tftpboot;bootm' would appear to fix this issue.
Not sure what the colorbar is all about
Hi Bernard Vachon,
Follow the steps mentioned in u-boot wiki page

Turns out that our dhcp server updates the tftp server address and bootfile name. So the "pxelinux.0" comes form our internal dhcp server.
