I'm working on an application based on iMX283.
I have the evk as a reference board + my own design. I'm trying to load eboot image using the sb_loader program.
The evk works fine, but I have a problem with my application.
The processor is connected to both 5V + battery.
The measured voltages are - VDDIO = 3.3V, VDDA = 1.8V, VDDD = 1.2V.
I've done a little research and found that the process fails in the BootFromBattery() function - where the DCDC is supposed to be enabled - this is the line (In the xldr.c) -
When trying to load eboot to my application – the process fails and the processor SHUTS DOWN when coming to Enable DCDC.
Running it with the DCDC Disabled – comes out OK.
Does anyone have an idea or suggestions for additional tests?
Thanks in advance,
