Part Number: WL1271-TIWI-BLE
Team,
Can you please help with the below request:
- The WL1271-TIWI-BLE (LSR research) is mounted to a mini module PCB that provide SDIO interface for the host board.
- The host is running Linux 3.14.52 kernel driver. With this kernel, WiFi driver works well but autocalibration steps, as described at the below link, doesn't.:
http://processors.wiki.ti.com/index.php/WL12xx_NLCP_Calibration_Process
The failing command is
calibrator plt autocalibrate <dev> <kernel mod> <ini> <nvs> <mac>
Now, we want to calibrate our module with default antenna using another board with an older kernel version where hopefully calibration steps works.
Q: Can you clarify which parameters are calibration dependant?
Are they dependant from chip design and used antenna or are system and environment setup modified?
Q: If they are dependant only from chip design and/or antenna, can we proceed to calibrate using another host board for mini module and obtain correct parameters for all boards that uses this mini module?
Q: If not, alternatevely, can we use calibration for R4_SP1 and earlier ?
It works, but we aren't sure that parameters are correct because we don't see any modification before and after doing this command
calibrator plt calibrate
Thanks in advance,
Anthony
