[U-Boot-Users] Production und U-boot
Hi all, I would like to have your views on how U-boot is used in production.
We will have Boards that has U-boot as the bootloader. U-boot will be burned in flash by means of JTAG. Later the boards will be put in a subrack for parallel SW download and Flashing.
Now what I am thinking of is to program U-boot to recognize a pin in the backplane, if the pin is set the board is in a production facility - BOOTP and a TFTP download of the flash image shall be done, and burned in flash ( by U-boot ). The pin is set by production staff.
If it is not set U-boot shall start a Image from flash ( Containing Linux and a Rootfile system ) since it is in a "sharp" environment.
Any other ideas?
Cheers // Matias

I've done similar things with our boards, mostly by setting a bootcmd_foobar variable in the environment (from misc_init_r()) when the pin is set and setting bootcmd to 'run bootcmd_foobar' in that case; this way you can test your scenario by running it manually from the command line.
If it is not set U-boot shall start a Image from flash ( Containing Linux and a Rootfile system ) since it is in a "sharp" environment.
The other thing I'm currently implementing is to setup a generic scripting mechanism which tests and flashed boards with an "expect" script - this works pretty well and you can also perform some test cases with U-Boot and Linux while setting up the board, including autogenerated test reports.
