program U-boot to SPI NOR flash.

Omega Gamage

I'm using EVM k2l device. It comes with u-boot pre-installed (on SPI NOR FLASH). I know how to load U-boot , but there we have some kind of command line interface to type some commands, and re-install U-boot.

But I want to know is How you pre-install U-boot into SPI NOR FLASH.

If we want to program U-boot to SPI NOR FLASH, how we can do it? Is there any software method?

Thank you.

If you want to update the u-boot on your board, there are several methods.
Set boot mode to "DSP no boot mode" and try to load the u-boot on MSMCRAM via UART, CCS.
Then you can update the u-boot (flashing the new u-boot to flash on SPI NOR or NAND)

Also if you have running the older u-boot, still you can update the u-boot to latest in older uboot itself.

tftpboot 0x88000000 u-boot-spi-k2X-evm.gph (X- where your platform name, k2h,k2l,k2e,k2g)
sf probe
sf erase 0 0x100000 (erasing flash offset 0 to 0x100000 )
sf write 0x88000000 0 0x100000 (write the u-boot from RAM address to SPI flash)

Please refer to the following TI wiki page.

Omega,

Board manufacturers typically have a way to pre-program the flash before assembling the SPI flash on the board. We provide them the image to be flashed on the SPI flash and they have utilities and the setup to program flash with the binary.

If however, a user receives a board where the SPI flash is not pre-programmed with u-boot image, we expect user to load u-boot over emulator as described here:

According to that I need following files, u-boot-keystone-evm.bin,skern-keystone-evm.bin,

But I could only found ,following at the ti-processor-sdk-linux-k2l-evm-03.00.00.04/board-support/prebuilt-images

keystone-k2l-evm.dtb, skern-k2l.bin,u-boot-k2l-evm.img, u-boot-spi-k2l-evm.gph, zImage-k2l-evm.bin

From where can I found u-boot-keystone-evm.bin,skern-keystone-evm.bin?

In processor SDK, files are renamed with platform name like k2h, k2e,k2l etc.,

skern-keystone-evm.bin -> skern-k2l.bin
u-boot-keystone-evm.bin -> To get the u-boot binary, you need to rebuild the u-boot source and you would get "u-boot.bin"
