Sylvania model synet7wid
June 17, 2024 06:21PM
so i came across this little netbook Sylvania model synet7wid with a VIA wm8505 chip, it shows the SYLVANIA logo on
the screen with Loading OS Image ... then after a few about 10 seconds it says loading device drivers ...
with a bar like the windows xp loading screen. it was supposed to have windows ce 6 and will not go any farther.
okay, so i took it apart and hooked a uart dongle for a com port interface to a pc and this is what i get...

so can this be fixed the way you all do your fancy repairs?

This is a hard one to do "fancy repairs" :) The NAND flash (which is where the system is) is bad. The saving grace is it's an ARM box and run u-boot. So you would need to find the FW first (backup or installation image). And in u-boot console, you would erase NAND, hoping that all the bad blocks are gathered and put away by the flash controller. And then flash it.

You could also consider installing a Linux OS on the device as it is supported by the mainline Linux kernel. See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/vt8500/wm8505-ref.dts which is the device file for Wondermedia WM8505 Netbook.
