How to recover u-boot?

Is there any place where I can GET u-boot image to recover this board?

Re: How to recover u-boot?

Hi buravW,

 

I have attached the factory image for U-Boot which you can program the factory default UBL and U-Boot images into the SPI flash using the TI SFH utility.  

 

To do this programming in production, we download a "helper" U-Boot via URAT boot mode so you will need to first set your boot mode jumpers to UART boot mode (DIP S7, pins 7 and 8 ON).

 

Since the board USB-UART gets enumerated as COM3 on that PC, we specify COM3 when running the SFH utility through this command:

 

sfh_OMAP-L138.exe -p COM3 -flash ubl_OMAPL138_SPI_MEM.bin u-boot-2009.1.1.bin

 

Once the SFH programming is complete, configure the 8-pos DIP switch for ARM SPI1 boot mode S7 as follows:  Switch 1 on, all others OFF.

 

Hope that this is helpful,
