Hello. I got in a switch that does not power on, it does negotiate 15v and charges the battery. When connected to tmy PC, tegra does detect rcm mode, but it’s a patched switch, so injecting a payload won’t do anything.
With my oscilloscope I probe the emmc clock line, and it’s just dead. Probing a non-working, misssing eemc board, I get a clock. So that tells me it doesn’t matter if this emmc is dead or not, I should still see a clock, which I don’t.
I do get all the normal voltages out of the PMIC on the back of the board. So it is recieving a signal to turn on, just no data being sent from the emmc to SoC due to a lack of clock.
Am I correct to assume the SoC is dead? As it is the clock generator for the Emmc?
