Hi,

I tested NAND boot for our iMX283 product at low temperature then boot failed about 1/80 set.
Error code was "0x8050100b" which means "Load command payload CRC failed".
Is there anyone can help?

 

(Q) Does it mean CRC of read data during LDR instruction period failed? Why this fail happen?

(Q) Which part of i.MX28 detect CRC fail? BCH hardware or software?

(Q) How can I avoid this CRC fail?

 

Thanks.
