Hi,
Has anyone run across an invalid DC_REGVAL while attempting to calibrate the lms rxlpf? I've been chasing after some alisaing issues and what appears to be a DC peak, in calibrating the radio I came across this error which prevented the operation from completing.
bladeRF> calibrate lms rxlpf
Calibrating LMS RX LPF modules...
[WARNING] Bad DC_REGVAL detected. DC cal failed.
Calibrating the individual components on their own completes fine, with the exception of the rxlpf.
I'm on the following builds:
bladeRF-cli version: 0.11.1-git-421b8d8
libbladeRF version: 0.16.2-git-421b8d8
Firmware version: 1.7.1-git-ca697ee
FPGA version: 0.0.6

Re: Calibration problems
Quick update. After a calibration the RX LPF Q filter is set to 0. The I filter looks like it was set during the autocalibrate:
bladeRF> calibrate lms show
LPF tuning module: 23
TX LPF I filter: 30
TX LPF Q filter: 29
RX LPF I filter: 35
RX LPF Q filter: 0
RX VGA2 DC reference module: 25
RX VGA2 stage 1, I channel: 29
RX VGA2 stage 1, Q channel: 29
RX VGA2 stage 2, I channel: 25
RX VGA2 stage 2, Q channel: 35
I am able to set it to an arbitrary value and subsequently read it back.

Re: Calibration problems
Hi there,
Admittedly, there are still known issues with the calibration, so I'm not terribly surprised. However, fixing RXVGA2 issues has been the current "work in progress"... I haven't seen the RXLPF act so weird like that. There's definitely more wrinkles to iron out in TX auto calibration, as well as the DC calibration table generation (e.g., accounting for DC offset variations with gain -- not just frequency).
Could you post the same output, but with running bladeRF-cli with -v verbose. This should show us the contents of LMS registers so we can try to understand what funny business is going on under the hood. To avoid a huge post, you can wrap the output in:[/code]
If you have access to another device, do you see different behavior?
Best regards,
Jon

Re: Calibration problems
I do have access to a second bladeRF for testing, this one is able to calibrate consistently. I do get the occasional '31's you've seen however this is fairly infrequent and I've had luck just waiting a moment then retrying the calibration. Due to the character limit on posts, the verbose output from this one is omitted. I will gladly post it if it's of any help.
The other bladeRF has not been able to calibrate successfully, it always seems to stop at the same place. A typical output from an attempted calibration looks like:

Re: Calibration problems
So as you described, I see the RX LPF Q calibration failing in this chunk of your log, as indicated by "module 50:01" (register 0x50, DC_ADDR[3:0] = 001).
The procedure being carried out here is described in Section 4.7 of the LMS6002D FAQ. After we get a 31 back in register 0x52, we retry with the value set to 0x00. According to that FAQ, no chip that passed LMS production tests should read back again 0x00 at that point.
However, given that we're still debugging that strange behavior with the RXVGA2 cal, I think it's too early to make any claim that the LMS chip is the definite cause. So unfortunately, I don't have a quick answer for you. I'll be getting back to debugging the RXVGA2 issue soon. Hopefully when we idenfity and resolve any issues there, we may find that what you're seeing is related.
The part of your log that I'm looking at for the above comments:

Re: Calibration problems
*bump*
I just had the same the error. My versions:
Edit: Note that I only had this problem on 1 of my 2 bladeRF x40's, and it's the one I'm using as a transmitter right now. My receiver SDR calibrated just fine.

Re: Calibration problems
Hi there,
As noted in this thread, we've been working on these issues. Some feedback on the latest changes to address these issues would be greatly appreaciated.
So give FPGA v0.1.1 a shot with the lastest libbladeRF from git, and let us know how it goes!
