i.MX 8M Plus DDR inline ECC configuration/documentation

Hello,

We are looking to implement ECC scrubbing on i.MX 8M Plus, but we find the documentation (IMX8MPRM, Rev. 1, 06/2021) to be lacking some critical information, namely:

1) ECCCFG0 - dis_scrub - note implies that scrub is not supported at all, since this SoC only supports inline ECC, so is it supported?

2) ECCFFG1 - data_poision_en - ECCPOISONADDR0/1 not documented

3) single-bit / multi-bit error counters, trigger levels, interrupt status etc. registers are not documented

4) scrub ranges, mechanisms etc. - these registers are used by U-Boot to do initial scrub, but not documented anywhere Where can we get this information?

Similar questions were posted month ago (https://community.nxp.com/t5/i-MX-Processors/i-MX-8M-Plus-DDR-ECC-documentation/m-p/1372898) and it seems that the documentation is still unavailable?

Thanks,

Philippe

Hello again,

Following this post the iMX8M Plus ECC was evaluated. Is this still the case?

Thanks,
