Linux/TMDXEVM8148: Programming bootargs using PCIe u-boot

Steven Sherbert
Intellectual 580 points
Part Number: TMDXEVM8148


Tool/software: Linux

Referencing the following documents:

http://processors.wiki.ti.com/index.php/TI81XX_PSP_U-Boot_PCIe_Boot_User_Guide#Components_Involved_in_PCIe_Boot

http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide

The documents mention that:

Bootscript: By default, U-Boot is configured to run a script from location 0x80400000 automatically. This boot script can have commands to set kernel bootargs and load kernel to carry out complete kernel boot automatically. Refer PSP U-Boot user guide for information about writing and creating a U-Boot script using mkimage tool.

All references to the procedures assume a command prompt and a TFTP connection.  PCIe u-boot does  not have either.

How does the boot script get programed into memory at 0x80400000 when there is no command prompt?

Is there a method to modify a default boot script that the PCIe u-boot will use when booting Linux?
