BOOT OPTIONS ON iMX8M mini board

[giacomobiancala]

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,

You can share your schematic on mrudang.shelat@volansystech.com. If you want you can remove the project name and customer name etc.

Hi Mrudang,

Sorry for my late answer. Finally I have defined boot options and all seems clear. If you have a private contact I can Share electrical schematics.

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?

Hi Giacomo,

Kindly share your schematic for CPU, eMMC, SDIO and Boot section.

This will help me to provide a complete solution of your query.

Hi Giacomo,

Any update?

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.
