Hi Robert, Seeed have not open sourced the board or software so I don't have any schematic, and in my excitement to find the standard image booting I flash it to the emmc with out working how to back it up first, so no default image for me (for now, if I get this to work, the unit fits my needs perfectly and I'll be getting more and more chance to get the default image).
My next challenge is to get the LoRa card working (top mPCIe connect on the side with the two mPCIe connetors). What I know is that the card is a RAK2247 SPI Concentrator module and I need to be able to drive pin 22 of the mPCIe to reset the card. So I need to find the SPI bus that it is connected to, any Ideas? I was thinking of finding/designing a mPCIe proto board and looping the rx and tx and doing some echo test. But the only one I can find with google is https://twinind.com/index.php/products/pci-express-products/mini-pci-express-adaptors/sh09mpe-pb1-pcb/ but that will end up costing me around $150USD by time I got it shipped to me. On the other hand seeed are able to make and ship to me 10 units for under $30USD, so just need to R&D (ripoff and deploy) a design and get in made. Then I need to work out what GPIO is driving PIN 22 of the LoRa mPCIe connector maybe to dtbo can give us some clues, I managed to decompile it with dtc (don't know if I did it correctly) and am still working out what it all means. But I am guessing it just the setup of all the pins, but how to drive them and what I'm going to let the smoke out of if I do is another question. But my current idea here is to drive the pins one by one till I see a change at PIN22 on the LoRa mPCIe connector (proto board would help here to, as well as some educated guessing). dtbo and decompiled dts attached -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
