Previously, I designed custom board with xavier nx, and there is a problem with HDMI. (I attached the schematic related with HDMI)
I was designed hdmi’s power source to attached with 5V, 3.3V directly
(VDD_5V0_HDMI_CON to VDD_5V0_SYS, VDD_3V3_HDMI to VDD_3V3_SYS)
it was pretty worked fine.
but after i changed HDMI’s power design, There was a big problem with hdmi.
When i turn on the device, it showed NVIDIA logo and after a few second, it showed its log for a moment(message related with some peripherals) and never turned off.
And after i changed design, it showed NVIDIA logo and after a few second, suddenly the monitor lost its signal.
And few second later, it showed ubuntu. but also after a few minute, it was suddenly turned off.
and after that, there was nothing on screen .
Even the monitor became turned on, its resolution turned into 1280 x 640 (original 1920 x 1080) (and SI1869DH-T1-E3 was extremely hot)
Is there somethings wrong with circuit ? (I think the SI1869DH-T1-E3 circuit has problem with current drain )
