Greetings, Pardon - the reporting - from post to post - seems 'inconsistent' - and that (never aids) your 'remote, diagnostic team.' Specifically: Display was reported to 'work fine' when operated under 'Non-µDMA' conditions. Yet today - we learn that 'physical connections are substandard.' No recognizable signal output occurred upon the SPI signal channels (stochastic noise, only) when first attempting 'µDMA-SPI Mode.' Later - too high a speed SPI clocks were observed - yet no explanation as to how the SPI signals were suddenly 'recovered.' Today we learn of 'jitter' upon the SPI clock (we are not 'so sure' of that) - yet that was never past reported. Now the process of 'MCU Display Diagnosis' is somewhat complex - and that is why - consistency in 'back & forth diagnostic efforts' and high responsiveness' prove vital. Minus proper answers to (what are believed to be) 'reasonable questions' - the diagnostic effort stalls. Our hope is that you can recognize - and understand this... I've linked our response to a similar 'Display Issue' - therein you will find (my firm's ability) to 'very well have predicted' your issues - as (now) reported here.
