Hi Taiidan,
Thanks for your message.
I am using v4.6 on my system FYI (no reason for me to update) and the only options I have changed are the ones I told you about before...all I can figure is perhaps I have a different version of the SP5100 that doesn't have the erratum or something to that effect.
Is it possible for me to build v4.6 in case something has changed since then that causes my issues? When I look at the branches available on git there is no 4.6 available.
FYI I saw you select build nvramcui as a secondary payload so you can mess with cmos options without recompiling as long as next time you shut off "Load default configuration values into CMOS on each boot"
Since your menuconfig options look fine...shot in the dark but try using grub instead of SeaBIOS as I use grub.
I will try building it with Grub. There is an option to include a GRUB2 runtime config file into ROM image. Should I select this? If so, what options should be in this file?
Kind regards,
Pete
