Dear Community,
I try to set up a basic flowgraph in GRC consisting out of a null source, a tx streamer and DUC and a TX radio. I use UHD4.0 and GR3.8.2. However, I get the following error message: RuntimeError: RuntimeError: Error during RPC call to `init'. Error message: RuntimeError: Receiver profile out of range RF bandwidth. I tried different settings for sample rate, etc. but still I get that error. I attached the used flowgraph. The second question is with regards to the default fpga images. When I download the images I get the following error: [ERROR] Downloaded SHA256 does not match manifest for https://files.ettus.com/binaries/cache/e3xx/uhd-2cba65b/e3xx_e310_sg1_fpga_default-g2cba65b.zip! 01137 kB / 01137 kB (100%) e3xx_e310_sg3_fpga_default-g2cba65b.zip [ERROR] Downloaded SHA256 does not match manifest for https://files.ettus.com/binaries/cache/e3xx/uhd-2cba65b/e3xx_e310_sg3_fpga_default-g2cba65b.zip! 10183 kB / 10183 kB (100%) e3xx_e320_fpga_default-g2cba65b.zip [ERROR] Downloaded SHA256 does not match manifest for https://files.ettus.com/binaries/cache/e3xx/uhd-2cba65b/e3xx_e320_fpga_default-g2cba65b.zip! 20729 kB / 20729 kB (100%) n3xx_n310_fpga_default-g2cba65b.zip [ERROR] Downloaded SHA256 does not match manifest for https://files.ettus.com/binaries/cache/n3xx/uhd-2cba65b/n3xx_n310_fpga_default-g2cba65b.zip! 14345 kB / 14345 kB (100%) n3xx_n300_fpga_default-g2cba65b.zip [ERROR] Downloaded SHA256 does not match manifest for https://files.ettus.com/binaries/cache/n3xx/uhd-2cba65b/n3xx_n300_fpga_default-g2cba65b.zip! 27285 kB / 27285 kB (100%) n3xx_n320_fpga_default-g2cba65b.zip [ERROR] Downloaded SHA256 does not match manifest for https://files.ettus.com/binaries/cache/n3xx/uhd-2cba65b/n3xx_n320_fpga_default-g2cba65b.zip! What can I do to solve that problem? Any help would be more than welcome! Thanks, BR, Anton
