To transition from low power mode to high power mode

[tamotsu]

I debugging IVT of i.MX7D.

The boot device is parallel NOR Flash using EIM interface.

After powerup, the CORE is going to read  the NOR flash.

However, it stop after reading 20 words because there are error in the content.

A message appears in the debugger saying that the 1V power supply is 0V and halt cannot be performed.

How can I set it to high power mode?

What bootloader are you using?

[tamotsu]

Hello jimmychan.

This is the state before bootloarder.

When the power is turned on, the built-in ROM gose to read the IVT.

Then the MPU ends up in the state of my question.

Best regards.

After POR, the boot ROM reads the IVT.

Please tell me what to execution with the boot ROM after an error occurs.

I solved it myself.

After changing the boot-device from NOR-FROM to QSPI, the Boot-ROM dose not enter Low-Power-Mode after booting.

Then connect the debugger and the connection was completed.
