It looks like the default voltage for the EIM interface is NVCC33_IO and I have a 1.8V FLASH device. Is there any recourse here? I can't boot to change the LVE bits.
I see the design notes say that I can power the 3.3V rail to 1.8V and then bump it up after I set the LVE values for the IOs, but there are some problems there:
1) I am using the PF0100 PMIC that has the correct power up sequence for my chip. I have already had to get a new PMIC (F3 version) to work around an errata on the imx6sl. I don't see how to make that chip power up the NVCC33_IO to the 1.8 in the right sequence
2) I could switch to a 3.3V FLASH, but I have other 1.8V devices on the EIM interface
Has anyone successfully booted an iMX6SL from a 1.8V NOR FLASH?
