Reply To: v.1.7 not working even after JTAG flashing; how to debug?
Hurray! it’s back after desoldering the audio ADC. I got no HDMI output at 1st because the U6 regulator was damaged and only outputting 1.7V. I fed U5 into U6 and got HDMI to work. I noticed the VGA signal was noisy around sharp edges, which is what you warned since analog power is supposed to be separate from noisy digital ones.
Very glad this unit was saved. Thank you very much Morpheus for the insights. Someone should check if the I2C code for the ADC will hang forever if the clock is pulled low indefinitely. I didn’t get to check before I desoldered.
