  • @mjones, Thanks for the information. We are working on verifying the pin states and using the code to reconfigure the expander now. Also, we give +infinity up votes for changing the flash/ spi bus architecture on the next rev. Since SD cards a…
    in Using EEPROM for application data Comment by jamorton January 2016
  • Hi @mjones, Thanks for your help. We are working on a test/ demo app right now that is trying to follow your outlined approach above. We are having some real trouble getting the flash to do anything. We have the flash programming/ readback and suc…

  • Thanks for the information @mjones We are configuring the FPGA from the BBB, so we essentially have all of the flash for application lookup tables.  Another issue we are trying to understand is if there is any way to run the SPI flash and SPI…

    in Use Logi-bone with EMMC mounted kernel Comment by jamorton September 2015
  • @jpiat I still haven't made a lot of progress on the issues in this feed. I did finally find an eMMC loaded kernel that would sort of work with the logi-bone however I have been having to manually compile SPI dto's for it.  However, my logi-bo…

    in Use Logi-bone with EMMC mounted kernel Comment by jamorton September 2015
  • Thanks Jonathan! Our development logi-bones are all R1.5.1. The other issue we are having (which I though was attributable to the GPMC/ eMMC conflict) was that we get the write error to ../at24/1-0054 (non-existant directory) when trying to ru…
