hello,Community


Figure 6-46 SD / MMC manufacture boot flow of i.MX 7 Dual Applications Processor Reference Manual is described in the reference manual.
For example, in the case of internal boot setting, if primary boot (for example, QSPI setting) fails, it proceeds to SDMMC MFG mode judgment.
After that, the default value is enable, so proceed to SDMMC MFG mode boot.
In SDMMC MFG mode boot, do you check boot sequentially from USDHC-1 to USDHC-3 regardless of how the allocation of USDHC is (SD or other than SD)?

 

best regards
