i.MX7 BOOT_MODE[1:0] power group.

[satoshishimoda]

Hi community,

Our customer have a question about i.MX7.
Please see Table 4 in i.MX7 hardware development guide (IMX7DSHDG Rev.0).
As per the Recommendation of No.1 of this table, BOOT_MODE[1:0] power group is VDD_SNVS_IN.
However, I think this is misprint since other documents (Table 88 in IMX7SCEC Rev.2, i.MX7 SABRE schematics) say BOOT_MODE[1:0] power group is NVCC_GPIO1.
Is my understanding correct?

Best Regards,
Satoshi Shimoda

Hello,

  "BOOT_MODE0, BOOT_MODE1 and POR_B are connected to NVCC_GPIO1
power domain internally, they shall be pulled up to NVCC_GPIO1, but not VDD_SNVS_IN.
Our EVK schmatic is correct and customers can refer to it for their new projects."

Have a great day,

Yuri
