Hi everyone,
Some time ago I ask you about NAND problems on u-boot over my M5329 freescale EVB. We solve it using the last u-boot (U-Boot 2008.10) compiling it with an M5329BFEE_config.
I though everything was going well, but some problems have appeared now. When I try to write on NAND device blocks of 512 bytes (the nand is and 16KiB pages of 512 bytes) everything seems OK, any error message.
But when I try to read the block, an error (-74) occurs in any block except the first one I've written on. If I take a look on the information written on every page I can see that ONLY the first page I wrote is written correctly. The other pages have wrong information inside them.
It doesn't matter if I write every page separately or in bigger blocks. U-boot only write correctly the first page that I attempt to write. Until I erase the whole memory.
Did you know anything about it? Could be my Flash memory chip be broken? I don't thing so, 'cause I can manage it correctly from ucLinux.
Thanks in advance.
