Flashing uboot onto P1024 without JTAG

[pavankumarg]

Hi,

I am currently using a P1024RDB .The board currently uses boot image from NOR flash. Does the P1024RDB support flashing of u-boot onto the board without a JTAG (serial or other methods if any). I want to flash my own u-boot image on the board for testing the peripherals.

Thanks.

Have a great day,

U-boot itself can program NOR flash. U-boot may download image into memory, erase flash and write image to the flash. Please see

The P1024RDB NOR flash can be split into two logical halves by setting the FBANK_SEL signal. The FBANK_SEL signal is controlled by setting SW4[8]. It also has NAND flash. So you can write your u-boot image without erasing the original.
