Hi, I want to back up my board's NAND flash to my host. I have a Ubuntu box and I have installed picocom on it. I am able to communicate with picocom and the supervivi menu is accessible. Whe I select u for backing up the kernel, it asks me to use DNW. I don't know how to go further. I don't have a windows computer. I have installed usbpush in /usr/bin. Also does the NAND backup include everything in the NAND? I mean if I install a new kernel, and it doesn't work well, can I revert to the old configuration by restoring the NAND? Thanks.
How to back up NAND from linux
I would expect if usbpush can put stuff into NAND it should be able to get it as well. DNW backups the whole image, everything. DNW allows you to restore previously saved images. Have a look here: http://groups.google.com/group/mini2440/browse_thread/thread/39fffdba68f...
I did something crazy. I installed virtualbox and created a win XP VM. Next I used picocom in linux to send the command [u] to supervivi and I used DNW in the VM to receive the backup. It worked!.....for a while. After about 93% transfer, I got err:31>>cancelled by host. It was painfully slow....450kbps I think, and I am stuck with 1 GB NAND!!!
