Hi All, I am working on the HackRf BBB prototype board. This is basically a HackRf One as a cape for the BeagleBone Black and Green. I have most of the firmware ported to the BBB but I am having problems confirming that the registers are getting written to the various chips. It appears that none of the read_reg functions actually read the registers but instead only send the contents of a register array in memory. I was wondering the reason for this? When I change the code to actually read the contents of the chip registers all I get back is 0. This includes altering the firmware on a HackRf One board and using the chip read utilities. Right now I can't confirm that I am actually communicating with the chips. Looking at the MISO and CLK lines with a scope confirm that the SPI is working. The datasheets for the various chips haven't shed much light on the problem so far. Does anyone have any ideas? RickKD0OSS
