Hello,
We are using the ADRV9002 with a custom board and are attempting to use the frequency hopping feature. The driver we are using is the one contained in the adrv9002 kernel branch - some very minor porting work was required to bring this into our local build and the driver is working well outside of frequency hopping.
TES 0.20.0 was used to generate a frequency hopping enabled profile. When the driver attempts to load with FH enabled, we see a delay of approximately 1 minute before the following messages are produced:
[ 72.254643] adrv9002 spi0.0: [ERROR]: Error number 3 (0x00000003), Recovery action -101.In file drivers/iio/adc/navassa/devices/adrv9001/public/src/adi_adrv9001_arm.c, in function adi_adrv9001_arm_CmdStatus_Wait, in line 678, variable name device.Error message ArmCmdStatusWait() failed due to thrown ARM error.

[ 75.197890] cf_axi_adc: probe of ff220000.axi-adrv9002-rx-lpc failed with error -22
After this point the driver fails to attach and the device is non-operational. Some investigation has found the failure is occurring somewhere related to the 'adi_adrv9001_cals_InitCals_Run' function call. I understand that the FH tables are supposed to be provided via sysfs, however the driver doesn't load to this point so I am not sure what other steps are required other than providing the FH enabled profile.
Any guidance would be appreciated.
Thanks,
Justin
