Mass Production Device Initialization

Mario Raffin

During the DM36x development phase, I use TI emulator to flash UBL and U-Boot, then I flash the kernel with tftp/nand erase/nand write and finally I flash the filesystem from the a tarball in NFS.

This procedure is quite long for mass production.

I would investigate about the commonly used procedure to init the NAND flash in such systems (UBL - U-Boot - Kernel - Filesystem).

Thank you!

Peregrinus,

Have you explored the options of bulk NAND programmers. Have a look at BP Microsystem programmers. http://www.bpmicro.com/Family-Automated-Production.html

Thank you Thomas.

I wonder how to flash the kernel and the filesystem together with UBL and u-boot with the jtag emulator.

Hi,

You can flash everything in only one step from SD card (if you have one on board) with sd_boot utility. It's more simple and faster than using JTAG.
The board has to be able to boot to SD card.
