Hi,
I need a clarification about boot options on iMX8M mini processor.
I am developing a custom Board based on iMX8M mini. I have 2 BOOT options.
- eMMC (on uSDHC3). In this case NVCC_NAND = 1,8V
- uSD port (on uSDHC2). In this case NVCC_SD2 =3.3V
I also have NVCC_SD1=3,3V.
I have some doubts about BOOT_CFG[6:4] and BOOT_CFG[3:1].
BOOT_MODE referred to 1,8V and the other pins referred to 3,3V. Is it ok?
Is it correct attached table?
Thanks,
Giacomo
Hi Mrudang,
Thank you for your answer.
I changed voltages domains.
In conclusion I have all voltage domains NVCC_xxxx at 3.3V (excepted NVCC_NAND for eMMC).
Moreover uSDHC for SD CARD is uSDHC1 instead of uSDHC2.
Did you read my attached BOOT pinout tables?
Regards,
Giacomo
Hi Giacomo,
Kindly provide Boot_Mode domain pin supply voltage. It should be the same power compatible with all BOOT_MODE and JTAG and Test_MODE.
What do you mean by other pins? Kindly provide the details.
If it is the same as a compatible supply for BOOT_MODE and NVCC_JTAG, then it is good to go ahead.
Regards,
Mrudang
