Reply To: [STILL AT IT] Think I fried it. Heard a sizzle.

Ok – I created a loop on “HDMITX_DevLoopProc” which i believe is a diagnostics function. I created a debug build and flashed it to the chip (had to disable the setup_rc() function for it to fit in memory).

Gave me the following output, it definitely detects the display after a connection, i think its down to the sending of a bad voltage on one of the pins of the twisted pairs causing the display to reject the signal. I’m going to replace the IT6613 and see what happens.

HDMITX_DevLoopProc
sysstat(REG[0x0E])=4Eh
