Re: [U-Boot] Can't read kernel if bad blocks are present in partition

2012-05-01 Thread Alexandre Gambier
Assuming you load the kernel to ram with tftp (and that "AppKernel" is an mtdparts partition in NAND), then you could do: nand erase.part AppKernel tftp $load_addr uImage crc32 $load_addr $filesize nand write.i $load_addr AppKernel $filesize nand read.i $load_addr AppKernel $filesize crc32 $load_

Hi, Did you use "nand write.i" to write the kernel and "nand read.i" to read the kernel? the ".i" tells u-boot to skip bad blocks... No I use "nand read $load_addr AppKernel" cause I didn't know we can use "nand read.i" - "help nand" doesn't display this information. I tried "nand read.i" and

[U-Boot] Can't read kernel if bad blocks are present in partition

2012-04-26 Thread Alexandre Gambier
Hi, I'm working on a STM chip under linux and U-Boot 1.3.1. Here's my problem. To boot linux up I load the kernel stored in a NAND device. If a bad block is present in the nand I can't load the kernel. To store the kernel I first erase the partition and write the kernel image. During the eras
