Hello,
I'm attempting to flash NAND from Linux on my custom hardware with a AM3352. From the Linux userspace I'm flashing NAND, and everything appears to be good, but when I reboot, I boot back into the original kernel. What do I need to do to flash NAND from Linux userspace?

Then after the reboot I check the kernel. The build date and revision should have been updated, but it still shows the old kernel.
RIM# uname -a Linux RIM 3.2.0-ts-armv7l #46 Mon Jun 12 16:06:45 EDT 2017 armv7l GNU/Linux
I know the kernel build date and revision will change because I can flash NAND from U-Boot and it works. I'm not able to get the process to work from Linux. Any Ideas?
Thanks,
-Michael
