Cobra II RPL


#1

Do I need to recompile *.elf file that got from Showcase? My board is Cobra II, and project from Showcase is for FEZ Cobra.
It seems to me that I do not need to recompile it, but after my first try my board became unresponsive and I had to reflash it.


#2

I’m quite sure you need to recompile it.
I also think that buildscript, linker file are different.


#3

I have a RLP function compiled for EMX and it works perfectly on G120. So recompiling may not be necessary, but surely it’s best to do it.


#4

I am following this guide https://www.ghielectronics.com/docs/50/rlp-enhanced, I don’t see where should I specify that it is G120.


#5

I had problems with my 1st steps with RLP on G120.
If I remember right Dat sent me some new files and then it worked.
But may be this was related to some firmware problem.


#6

Can anyone tell me if I need to specify for which mainboard *.elf file will be generated and if so where should I do that?


#7

I’m not sure if you need different elf’s for different boards,
But if, then you just add them with different names to your resources like:
XMas_G120.elf
XMas_EMX.elf

The when loading elf, you check which board is on your shelf :whistle: (There are some SKU, … identifiers to read, which returns a specific id per SoM)
and read the elf that fits the board.
I have to fire up my working laptop, then I could post a simple RLP sample for G120 which actually works.

Edit:
I just posted a simple RLP sample for G120 on codeshare:
https://www.ghielectronics.com/community/codeshare/entry/843
It shows how to use inputs, interrupts and RLP events.
The usage sample shows the managed C# side of the code.

Thanks a lot for your code! I have finally made it working, not sure exactly how, but it is working :slight_smile:
