Linux: Possible to flash NAND from Linux userspace?

Tool/software: Linux

Hello,


Looking at this wiki for the BeagleBoard Black, I noticed a comment which said both u-boot stages could only be flashed via u-boot. Does this mean they could not be flashed via Linux userspace? I'm able to successfully flash NAND from u-boot, but I'm looking at moving this process to be done at Linux userspace and now I'm wondering if it's possible. My hardware is a custom board with the AM3352.

Kernel

While X-Loader and U-Boot can be written only by U-Boot, for kernel and file system there are two ways to write them to NAND: Either by U-Boot (similar way as for X-Loader and U-Boot above) or from running kernel (e.g. booted from MMC card).

 


Thanks.
