Hello. Problem when launching sd card USRP E310 after burning USB stick using toolbox. The console output looks like this:
U-Boot SPL 2017.01 (Jan 22 2020 - 17:58:15)
mmc boot
Trying to boot from MMC1
** Partition 1 not valid on device 0 **
spl_register_fat_device: fat register err - -1
spl_load_image_fat: error reading image fpga.bin, err - -1
spl: error reading image fpga.bin, err - 1
** Partition 1 not valid on device 0 **
spl_register_fat_device: fat register err - -1
** Partition 1 not valid on device 0 **
spl_register_fat_device: fat register err - -1
spl_load_image_fat: error reading image u-boot.img, err - -1
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
TRX-B Led is off. The board responds but fails to read the data. Tell me how to solve this problem. Flash drive format FAT32

I also want to ask you if there are any examples for creating receiver projects based on USRP E310. I want to make an amplitude direction finder.
FPGA: Window FFT GPIO Finding the maximum with N switches
ARM: Spectrogram reading and post-processing and display of azimuth and spectrum on a PC
PC: Display
Tell me what examples and documentation you need to study for this. I am new to this and have previously worked with GNUradio. Thanks in advance.

Ivan,
Apologies for the delayed reply. As a recommendation for the future, it's best to start a new thread when asking separate questions, since we might miss replies to the original one.
With respect to your question, the best place to start would be the Hardware-Software Co-Design examples. Specifically, Target an ADS-B Airplane Tracker Using USRP E3xx and HW/SW Co-Design Workflow demonstrates how to partition an ADS-B decoder algorithm between the FPGA and ARM. You could use the Receiver algorithm as a starting point, implementing your:
  • FFT on the FPGA
  • Post-processing and UDP Send on the ARM
  • UDP Receive and visualisation on the host PC
Best regards,
Gavin

Your SD card should have 1 partition formatted with a FAT32 or FAT16 filesystem.
To manage SD card disk partitions, try
  • Linux: fdisk
  • Windows: Disk Management tool
If making any modifications, ensure you have selected the correct disk (SD card).
Best regards,
Gavin
