Function of the JP3 jumper

[LejonD]

Hello Nick,

Question what is the function of the JP3 jumper?
The JP2 is for disable/enable
The JP1 is for the LED.

So could you explain.

JP3 connects /IFRST, which is the buffered /RESET signal from the CDTV to the STM32 reset input. Closing it will reset the STM32 whenever the Amiga is reset.

Could you also tell fot the TF-Holder, the card detect is it a open signal when (Micro)SD card is in or a closed signal when (Micro) SD card is in. Closed line is pulled to ground, or line open.

Well, on my prototype inserting the card pulls it to ground, with no card its floating. Given that, you need to activate the builtin pullups on the stm32. I assume BiueSCSI does exactly that, because it worked out of the box with the prototype.
