Hi,

I am having an issue while flashing.i am using an imx8mp processor.

Hi,

Thank you for your interest in NXP Semiconductor products,

In your setup do you use a custom board or an i.MX 8M Plus EVK? If you are using a custom board I would advise to modify the necessary code, focusing in memory and power necessary differences. Then confirming your porting is valid and being applied.

The error is seen when using an invalid imx-boot firmware image, another reasons can be defective cables or some USB power sources reset, you could try using a wall mount USB charger.

Hi @JosephAtNXP ,

Sorry for the inconvenience,it was a simple current shortage that caused the issue,when i raised the current to the required level,everything is working fine.
