LDR pins on G400... Required or not?

[Simon_from_Vilnius]

I’m designing a new G400D based board, and accidentally found this text in one of your documents:

Although there are “LDR1” and “LDR0” buttons on the FEZ Raptor, they currently (as of NETMF and Gadgeteer Package 2013 R3) have no function regards updating TinyBooter. A piece of the underlying low level code needs to be added before the buttons can be used for entering loader mode. This unimplemented software has absolutely no relation to the functionality of TinyBooter, TinyCLR and/or .NET Micro Framework.

So… Will they be implemented or not? I want to have all the signals in a single connector (USB, power, reset, plus all those custom buttons), and I have a really limited number of pins. If I’m using PA11 to put G400 into bootloader mode, why would I need another two extra signals? Or maybe I don’t?

We would love to see and plan to have these function just like they do on g120. No guarantee or timeframe though. I suggest having them exposed.

Well, I would love leaving them exposed, but I’m short on pins for my MiniDIN connector… And then there’s PA11. Exposing 3 pins just for reflashing is a luxury. And what about PA11? Will it stay? If you decide to implement LDR0 and LDR1 one day, then what happens to PA11?

[Gus_Issa]

I would still add them, minimum on test pads or header

Ok… Got it.

Any reason that they can’t be shorted together to a single pin?
