silicon revision

[FelipeBalieiro]

Hello,

I looking for some documentation regarding the silicon revision from MCIMX6S4AVM08AC to MCIMX6S4AVM08AD.
What change in this silicon revision? I not found any documentation about that.

Hi @FelipeBalieiro 
Please refer this datasheet.

https://www.nxp.com/docs/en/data-sheet/IMX6SDLAEC.pdf

The datasheet confirms that MCIMX6S4AVM08AC covers silicon Rev. 1.2/1.3, while MCIMX6S4AVM08AD is Rev. 1.4, a new 4N81E mask set with ROM modifications.

The related ROM modification can be found from here: Chip Errata for the i.MX 6Solo/6DualLite

Best Regards,
