Clarification request on wl18xx wiki page

Hi Tony,

For (2), please goto: http://processors.wiki.ti.com/index.php/WL18xx. There is a section called "Calibration And Testing". You should be able to find the relevant information there.

For (1), I believe they are internal variables - but I will get back to you on this.

Regards,
Gigi Joseph.

Thank you Gigi.

3) Can you also please confirm the  git branch I should use to build wlconf. I am using the binary built from the master branch(https://github.com/TI-OpenLink/18xx-ti-utils.git). But my driver (ol_r8.a6.02-dirty) does not seem to like the conf file generated. I get the following error.

"[   16.828110] wlcore: ERROR configuration binary file version not supported, expected 0x00060006 got 0x00050006"

The conf file was generated using the following command from the wiki.

./wlconf -o /lib/firmware/ti-connectivity/wl18xx-conf.bin -I official_inis/WL8_System_parameters.ini

4) Is the syntax for Tx Tone test correct in "http://processors.wiki.ti.com/index.php/WL18xx_TX_Testing#TX_Tone_Test_.28up_to_R8.3.29"
The command 
 "calibrator wlan0 wl18xx_plt tx_tone"
 and 
"calibrator --debug  wlan0 wl18xx_plt tx_tone 1 4000" (from the help menu returned from above command).

They both return the calibrator Usage help menu.

Thanks,
Tony

Hi Tony,

(3) Please reset 18xx-ti-utils to "ol_r8.a6.02" and retry (git reset --hard ol_r8.a6.02)
(4) Please replace "wl18xx_plt" with "plt" and retry.

Regards,
Gigi Joseph.

3) Thank you Gigi, I don't see the version error any more.

4) calibrator wlan0 plt tx_tone return missing argument error

plt_tx_tone> Missing arguments
failed to handle

I will have a look at the code to see what argument it is expecting as well.

Hi Tony,

Regarding question (1) - they are internal variables...

Please find below more information.

1 - a: The system supports 4 preconfigured power levels. Since they are symmetrical, we use in PLT only power level 0.
Recommended value: 0

1 - b: For scan (non-serving mode)we calculate power for the basic rate groups only, and this flag should configure this. Currently it is not supported.
Recommended value: 0

Regards,
Gigi Joseph.

Hi Gigi,

         I think for question (4) I had to add 'dev'  before the device name.

"calibrator dev wlan0 plt tx_tone 1 3"

But what are the arguments

"<tone type 1|2> <power 0 - 10000> ?

a) Is tone type same as that of 'mode' in 'tx_tone_start' (http://processors.wiki.ti.com/index.php/WL18xx_TX_Testing#TX_Tone_Test_.28From_R8.3SP1_and_above.29) ?

b) Is power the same as <output_power> in 'set_tx_power' (http://processors.wiki.ti.com/index.php/WL18xx_TX_Testing#Method_2)?

Thanks,

Tony

Hi Tony,

(a) Yes
(b) Yes

Gigi Joseph.

Thank you Gigi

Hi Gigi,

              I have been playing with the tx tone when I realised 'power' value(4b) cant be same as <output_power> in 'set_tx_power' (http://processors.wiki.ti.com/index.php/WL18xx_TX_Testing#Method_2 unless the values are limited?

For example as per the description of "set_tx_power" 16.125dbm should be 16125 (which is more than the maximum limit '10000' for 'tone type 1|2> <power 0 - 10000>' )

Is there a restriction on the value? What is the power argument equivalent to 16.125dBm?
