I am currently updating an existing i.MX7 design to i.MX8M.
The i.MX7 uses QSPI as boot device.
I used MCIMX8M-EVK schematics as reference and found the BOOT_CFG configuration for boot using SD, eMMC, NAND,QSPI and SPINOR. In the reference manual I only find BOOT_CFG for SD/MMC and NAND boot.
Is there no more support for other boot sources than NAND, SD and MMC?
who can you share how to repeat configure step ? Thank you
Hello,
yes, i.MX 8M supports only NAND, SD \ [e]MMC as boot options.
Have a great day,
Yuri

Hi YuriMuhin_ng,
Then why does the TRM says:
1.6 Primary Boot Options
The i.MX 8M Dual/8M QuadLite/8M Quad supports the following boot devices:
Also in the 6.2.1 Boot Fusemap clearly states SPI NOR as well as QSPI (BOOT_CFG[14]).
Isn't it only the Internal Boot that is limited to NAND and SD/eMMC? Then using Boot from Fuses allows for more options?

Hi Yuri,
Thanks for the clarification. What about the section 6.2.1 Boot Fusemap, is it also a bad copy/paste?
What about Table 6-19 which also mentions SPI NOR?
Thanks,
Gary
