In Pluto SDR, PL reprogramming from Linux crashes IIO streaming

Hello

 

My name is Danil.
I am very excited about the new Pluto SDR, it works very well.


I'm actually working on my own custom PL image for Pluto SRD and want to replace original system_top.bit. I want to reprogram PL using command in Pluto SDR Linux shell:

cat ./custom_top.bit > /dev/xdevcfg

As first, I'm trying to use original system_top.bit from plutosdr-jtag-bootstrap-v0.22.zip archive, which I download here Releases Tag v0.22. But after cat ./system_top.bit > /dev/xdevcfg I have problem with ad9361-iiostream and iio_adi_xflow_check programs.

 

I got following errors:

 

(1)
# iio_adi_xflow_check iio:device3
Monitoring cf-ad9361-dds-core-lpc for underflows/overflows
Unable to push buffer: Connection timed out

 

(2)
# iio_adi_xflow_check iio:device4
Monitoring cf-ad9361-lpc for underflows/overflows
Unable to refill buffer: Connection timed out

 

(3)
# ad9361-iiostream

* Creating non-cyclic IIO buffers with 1 MiS
* Starting IO streaming (press CTRL+C to cancel)
Error refilling buf -110
* Destroying buffers
* Disabling streaming channels
* Destroying context

 

I also done re-init in Linux, but it doesn't solve the problem.

 

# /etc/init.d/rcK
# /etc/init.d/rcS

 

For me is important to reprogram Pluto SDR PL part with Linux.
How can I do that?

 

Any help appreciated, thanks.
