External Reference Clock

[0x657373656C6C]

Hi,

With the success in getting the external reference clock working in the UHD firmware can this success be repeated in the IIO firmware. In particular, my findings show:

1. Reference clock is not detected in 0.34:

d9361 spi1.0: Calibration TIMEOUT (0x5E, 0x80)
ad9361 spi1.0: Calibration TIMEOUT (0x247, 0x2)
ad9361 spi1.0: Calibration TIMEOUT (0x287, 0x2)
ad9361 spi1.0: Calibration TIMEOUT (0x5E, 0x80)
ad9361 spi1.0: Calibration TIMEOUT (0x5E, 0x80)
ad9361 spi1.0: Calibration TIMEOUT (0x5E, 0x80)
ad9361 spi1.0: Calibration TIMEOUT (0x5E, 0x80)
ad9361 spi1.0: Calibration TIMEOUT (0x5E, 0x80)
ad9361 spi1.0: Calibration TIMEOUT (0x5E, 0x80)

2. Clock implementation seems missing in 0.35, 0.38

Can this be fixed?

Regarding the 10M clock lock of IIO, it has been implemented in the v0.38 version, but it requires additional operations in driving the ad5660 IIO device.

Hello,

By the way... how to check whether external clock (PPS) is available on E310 or not? I have plugged PPS from GPSDO, but can not see any synchronization info in /sys/class/pps/ (an empty dir) nor in $(dmesg) output. Firmware is v0.39 (IIO)

Regards,

Is there documentation on configuring IIO firmware to use an external clock?

关于 IIO 的 10M 时钟锁定，它已在 v0.38 版本中实现，但驱动 ad5660 IIO 设备需要额外的操作。
您好可以请问一下Antsdre310v2如何升级到0.38版本，驱动ad5660IIO设备需要啥额外的操作

hi was anyone able to figure out how to use the external clock on the e200?

i would've used the uhd version but my application needs to be standalone (without host just the znyq7020)
