So my first question...Is the nand being used for anything at this point now? Its unclear to me if arch's uboot is chainloaded from mtd0 or if its entirely independent of the nand all together. In either case I have no intention of ever reverting to the stock fw so would it be possible/(un?)wise to use the nand as a swap space? I was thinking of trying to recompile the kernel with CONFIG_MTD_SWAP enabled. I know that nand is far from the best media to use as a swapspace but for this im just intending on enabling it during compilations and other resource intensive applications i.e. it wont be on 24x7.
tldr...If I have arch installed on a sata drive can I completely wipe the nand? If not completely can I wipe mtd1-5 if I need mtd0 for uboot?
Second question...I have yet to pop the cover on the pp so I have next to no idea of what is integrated into the SoC and what is onboard (aside from the obvious i/o ports, buttons, power, etc...). Does anyone have a decent pic of both sides of the ppv4's board? I googled it for a while and couldnt find anything that wasnt just a partial or lo-res. My main intrest is the on board ram. If it isnt integrated into the SoC then im planning to hot-air a decent sized replacment on. (If it is integrated refer to my first question
) . Has anyone attempted this before? Does anyone know the manufacturer/pn or have a datasheet handy? More importantly (and a hard learned lesson attempting the same on a puma5 cable modem) are there any sort of restricitions in the uboot image to limit the device to certain part numbers?Thanks for your help and thanks for a great distro to mate with this interesting device!
