Hello,
I try to write to my NAND flash and for this I tried different things. One is to use the U-Boot functionality and the other to use linux functionality (other thread). If I do it as described at the manual I always get an error and I do not know why. See the procedure here:
=> tftp 1000000 u-boot.bin
Speed: 1000, full duplex
Using eth0 device
TFTP from server 192.168.0.11; our IP address is 192.168.0.111
Filename 'u-boot.bin'.

My system environment is :
- Ubuntu 11.04
- I use currently the Freescale toolchain with bitbake and built the images as described in "Freescale Mentor Embedded Linux Essential for QorIQ Processors, Rev 1.0.1"
- P2020RDB-PCA evaluation board
Does anyone know what the problem could be and how I can solve this?
Thank you very much for your help.
