Its booting to DiagROM but kinda unreliably. Mind you it has no caps on at all at the moment.

Grim reality is that I am a single parent for the next 4 weekends :( can’t see me getting much work done on the TF360 r1

I may start on the TF1260

Well i dont really make any money on each board so number of sales isnt really a factor.

OK there is an issue with the Rev1. I cannot choose the "M" value for the clock speed selection. Seems we're 0.7V above VDD/2

https://docs-emea.rs-online.com/webdocs ... 2e26b3.pdf

Most likely the CPLD has something internal (maybe part of the 3.3V tolerant stuff) thats pulling the voltage up to 2.39V

So I am going to try some inline resistors to see if that helps. I measured the peak input current at 0.3mA so a 0.7V drop over that would be between 2K and 5K.

Either way the current Rev1 will be scraped for a rev1b..

Any progress with adding resistors and seeing the result? I know you said you have child care priorities.

I am impressed you find the time. Just getting one 4yr old to brush their teeth and get to sleep can be an energy sapping experience :x :lol:
And so many cool project keep appearing to build & follow. It's a great time to be a retro hardware owner Mod/Hack/Enjoy 8-) :geek:
