Unable to calibrate WL1273L - fail with radio status -90

carlpii

I am unable to run the calibration process on a TiWi5 (WL1273L) based design. Calibration fails with the error message:

Fail to calibrate ith radio status (-90)

I get the same error on all of my prototype boards. The boards appear to work fine otherwise. I am able to connect to both 2.4GHz and 5GHz networks and transfer data without any apparent problems.

The boards are based on the DM368 running the IPNC 5.1.0 code base (2.6.37 kernel) plus the compat-wireless drivers built using the tools at github.com/TI-ECS/build-utilities.git. I set gen_tag in wl12xx_build.sh to ol_R5.SP7.01. I have tried this with and without the additional patches listed on LSR's TiWi5 support page. I have also tried replacing two of the WiFi modules with parts from different lots but always get the same error.

Thank you for your assistance,

Hi Carl,

Please ensure you are following the steps mentioned in: processors.wiki.ti.com/.../WL12xx_NLCP_Calibration_Process (rmmod wl12xx_sdio, ini file, etc).

Also, please share the complete logs.

Regards,
Gigi Joseph.

Hi Gigi Joseph,

Sorry if I wasn't clear - yes I followed the calibration process. The logs are below along with the steps I used to try to calibrate the module. I've tried using both the .ini file supplied by LSR and the one from TI that comes with ti-utils. I have also tried various manual calibration steps. Notice that it succeeds with single band calibration but not dual.

Thank you,

-Carl

Hi Carl,

This indicates something wrong with the ini file only - Anyway, let me check internally and get back to you.
Can you share the ini files that you have tried?

Regards,
Gigi Joseph.

Here are the two .ini files I have tried - Thanks,

Do you see any issues with the ini files? Any other thoughts on what could be causing this issue?
Thanks,

Hi Carl,

A few questions so I can better assist:

1. Which module exactly are you using?

2. Are you working with RTTT/TrioScope tool? If so we would like to get some inputs from there.

3. Do you have access to the FEM pins? If so we would like to monitor one of them.

Once you provide the answers we'll be able to support some debug steps.

Best regards,

Oren Shani

Hi Oren,

1) The module is an LSR TiWi5 which is based on the WL1273L. Please see my initial post for our full configuration.

2) I do not have the RTTT/TrioScope tool. If it would help debug this issue, can you point me to a source for it?

3) I'm sure I can remove the cover from one of our modules. What would you like me to monitor?

Thank you,
-Carl

0 Oren Shani1 over 10 years ago in reply to carlpii

TI__Prodigy 650 points

Carl,

2) As for the RTTT/TrioScope tools - it requires access to the RS232 lines on your WL6 chip. Please check if you have access to those lines. They should be exposed on the module...

3) If you get access to the FEM you should try to monitor and save an image of pin 11 which is PDET (power detector line of the FEM).

For more questions related to debug of your specific module and design you can also address my email: orenshani@ti.com.
This will allow you also to share your module and board scheamtics.

Regards,
Oren

Hi Oren,

2) I have been able to use the WLAN Eval Tool available on the LSR website which uses the Rx/Tx signals from the module. I can calibrate the module using that tool but it still fails with -90 using the Linux calibrator tool. Unfortunately, the WLAN Eval Tool is not a workable production method for calibrating the modules.

3) I'll see if I can get a scope shot of pin 11.

Thanks,
-Carl

TI__Prodigy 650 points

Hi Carl,

2) I was not familiar with this LSR Eval tool so I downloaded it myself from thier website. Basically it looks like a limited edition of the RTTT tool I was talking about. Just to verify: you used the 'Run TX BIP' button and same FW version as you used on the Linux?

I will try to see if this tool can help us and if not i will share with you the RTTT tool.

3) I am waiting for your update on that.

By the way, the -90 you're getting indicated a fail on BIP procedure of the first sub-band of the 5GHz band.

Regards,
Oren

Hi Carl,
I reviewed your log file a little to understand exactly how you are running the plt commands.
I noticed that you are running the following command:
./calibrator plt calibrate dual

It's been a while since I ran this process...can you tell me where did it say to include 'dual' for this command?
As far as i rememebr you don't need to use it for dual band calibration as long as you're using the right (dual) INI file.

By the way, please try to use also the following command which is just for the BIP process:
calibrator wlan0 plt tx_bip
(taken from here: linuxwireless.org/.../calibrator)

Regards,
Oren

0 carlpii over 10 years ago in reply to Oren Shani1

Intellectual 500 points

Hi Oren,

2) Yes, I used the Run TX BIP button but it only works with the WLAN Firmware (480-0027) also available from the LSR website. It does not work with the PLT firmware that came with the Linux compat-wireless driver build.

3) I should have time to remove the lid from a module tomorrow.

Regarding the calibrator tool: I used the "dual" flag based on the calibrator help information. The source code seems to confirm that although the autocalibrate command does use the ini file contents to select single or dual band calibration, the calibrate command does not. If I don't use the "dual" flag, the calibrate command succeeds but only calibrates 2.4GHz.

I've looked at tx_bip and other commands but don't know what parameters to use. If I skip the ref_point command and use tx_bip 1 0 0 0 0 0 0 0 <file>, it succeeds but based on the calibrator source, I believe this is only single band again. If I use tx_bip 1 1 1 1 1 1 1 1 <file>, it fails with -90 status again.

Thank you,
-Carl

TI__Prodigy 650 points

Hi Carl,Can you please do the following:
1. Try to access pin 11 of the FEM and capture it's behaivlr during BIP process.
2. Send us your schematics for review
3. Run TX_BIP one sub band at a time (use command 'calibrator wlan0 plt tx_bip' binary inputs to mask sub bands).
Thanks,Oren Shani

0 carlpii over 10 years ago in reply to Oren Shani1

Intellectual 500 points

Hi Oren,

1) I am waiting on our CM to remove the lid for me. I'll attach a scope picture when it's available.

2) I'll send schematics separately

3) I tried the tx_bip command with one bit set at a time. All but the first bit failed; the failures are consistent. Four of the commands fail with -80 status but three result in "wl12xx: ERROR command complete timeout" which causes an exception. I have to remove and reload the wl12xx kernel modules to continue. The log is attached below. Is this a driver issue?

Thanks,

-Carl

Hi Oren,

Here are a few scope shots of the PDET pin during calibration. The first two pictures are from the 'calibrator plt calibrate' command which I believe only tries to calibrate the 2.4GHz band. PDET2.png is an expanded view of the same capture. PDET3.png was captured using the 'calibrator plt calibrate dual' command.

I've sent the board schematics separately to your email address.

Thank you,

-Carl

Hi,

I am sorry to start from the beginning but can you please answer several questions:

1. We haven't received the schematics yet - can you please provide them?

2. Can you please confirm that the device is WL1273L: WL1273LYFVR PG3.32 vs Frontend RF module :TQP6M9002?

3. Can you please operate the device in operational mode and see if you are able to connect to some AP on 5 GHz?

4. Can you please redo the trial's again band by band (5 GHz only) using the following set of commands and using the ini file below?

Expert mode

calibrator wlan0 plt power_mode on

calibrator wlan0 plt ref_point <voltage> <power> <subband> -Alexey the reference point should be taken from the ini please set it.

calibrator wlan0 plt tx_bip <0|1> <0|1> <0|1> <0|1> <0|1> <0|1> <0|1> <0|1>

calibrator wlan0 plt power_mode off

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/968/TQS_5F00_D_5F00_1.7.ini

Thanks,

Alexey

Hi,

In addition on number 4 can you please capture the calibration again (using the 2 commands each time( setting ref point, tx_bip) - we would like to see each calibration(each sub-band) on scope separately ( if it possible can you please keep higher resolution on the Y axis so it will be more clear).

For each of the sub-bands please take the reference from the ini ( the following parameters):

FEM1_TXBiPReferencePDvoltage_5G = 019A 01AE 01C2 01CC 01DB 01DB 01D1 # Length: 7; Unit: 1mV; Format: Unsigned; Source: TI; Comment: This parameter define the reference point of the FEM power detector
FEM1_TxBiPReferencePower_5G = 80 80 80 80 80 80 80 # Length: 7; Unit: 1/8dB; Format: Signed; Source: TI; Comment: Reference output power that produces given reference power detector output voltage .

Thanks,
Alexey
