Dear team,
I would like to ask about the necessity of external 32.768KHz crystal oscillator of i.MX6D/Q.
My customer plans to use i.MX6D/Q for their system and they tend to use SD/eMMC boot.
In that case, is the external 32K crystal needed?
The customer has a concern on the impact by ERR07926.
Thanks,
Miyamoto
Hello,
You may look at erratum ERR007926 (ROM: 32 kHz internal oscillator
timing inaccuracy may affect SD/MMC, NAND, and OneNAND boot) workarounds.
Using external stable 32 kHz clock input or crystal oscillator are possible and most
universal (and recommended) solutions.
Regards,
Yuri.
