Is it possible to reload u-boot on TWR-P1025-KIT

I am planning to buy TWR-P1025-KIT . Its preloaded with U-Boot. the manual says it only supports NOR flash boot

I will be modifying U-Boot code and do R&D with it.

Without any JTAG adapter, is it possible to reload U-Boot on it if something goes wrong ?

Hi,

I'm afraid no. This board doesn't have a PROMJET or SD boot capability (only NOR boot).

Regards,

Marius

You can partition your flash into different halves. You may use a different flash halve to boot when your first flash halve U-boot has corrupt. This is the case with normal evaluation boards.

Instead i can go for P1025RDB-PA if i need to work on bootloaders (u-boot).

P1025RDB-PA supports booting from SD/MMC,NOR,SPI,NAND

So if i screw-up the u-boot on NOR, i can use SD (using u-boot) to boot the board (and reflash NOR if needed), right ?

That's correct.
