I have a custom board designed based on the i.MX23 CPU. I am powered from 5V DC without the Battery input, I am unable to powering up
VDDXTAL has 1V, crystal is oscillating at 24Mhz but the DCDC converter is not turning on and also Linregs (VDDIO, VDDA, VDDD, VDDMEM)
I am using the reference design i.MX23 Reference schematic rev C
I need to burn some bit to power up?
How can I debug the startup process?
Thanks for any advise
