I already tried that but it won't boot for me. Maybe additional info related to barebox env needs to be written. I am trying by sending UTP commands from MFGtools: UTP: received command '$ flash_erase /dev/mtd0 0 0' UTP: executing "flash_erase /dev/mtd0 0 0" Erasing 128 Kibyte @ 39002e0000 -- -1 % compl[ 6.275463] utp_poll: pass returned. Erasing 128 Kibyte @ 64004e0000 -- -1 % complete UTP: sending Success to kernel for command $ flash_erase /dev/mtd0 0 0. UTP: received command 'send' UTP: sending Success to kernel for command send. UTP: received command '$ nandwrite -p /dev/mtd0 -p $FILE' UTP: executing "nandwrite -p /dev/mtd0 -p $FILE" Writing data to block 0 at offset 0x0 Writing data to block 1 at offset 0x20000 Writing data to block 2 at offset 0x40000 Writing data to block 3 at offset 0x60000 Writing data to block 4 at offset 0x80000 UTP: sending Success to kernel for command $ nandwrite -p /dev/mtd0 -p $FILE. [ 6.823965] utp_poll: pass returned. I am writing a barebox.bin using nandwrite but it seems the new barebox(which is correct should boot) won't boot. So I am wondering if the nandwrite command is enough? I know nandwrite you can use it successfully for flashing roots or kernel on mtd partition but maybe for the bootloader is not working Thanks, Mihaita > This works for me, and there's probably some documentation for this > around, but i do not recall where i found it anymore. > > good luck > Andreas _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
