Other Parts Discussed in Thread: UCD3138
Hi Experts,
I refer the file to implement program upgrades with UCD3138.
Using D1D4 and PMBus for Program Upgrades in the field.pdf
The power have main output in normal, but one I/O pin is unusual.
Then, power off.
Once again power on, the power is in boot flash, I use Memory Dump to read main program.
Main program is erased and data is FF.
What happened to cause main program to be erased possibility?
Thanks!
