Re: [agl-dev-community] AGL HH on H3 + KF

["Stephane Desneux" <stephane.desneux@xxxxxxx>]

Hi Joel,

As I understand the chapter on https://elinux.org/R-Car/Boards/H3SK#Known_Issues
pointed by Mark, you can fix your H3 by flashing the CPLD with a Windows tool
(#!?*$ ... why Windows?????????? - anyway... I'm sure you have one at hand :)).

This way, you can avoid a board swap on KF.

Also, it would be good to have a confirmation that this procedure solves the
issue on M.2 NVME bus.

Please keep us posted :)
