Installing silverblue on uefi (32bit uefi 64bit baytrail processor)

I am failing to install Silverblue on that baytail computer…
Would you have eventually some advises?
I tested:
Direct commands after partitioning, before “Begin installation”: # mkdir /boot-temp # mount /dev/sda1 /boot-temp # rm -r /boot-temp/EFI/fedora # umount /boot-temp

as suggested in:
1575957 – Silverblue installation fails when the EFI partition isn’t reformatted 1
but that didnt work either…
anyone with experience on this?
I wish to let the automatic partitionning…
