No wireless TX possible

Other Parts Discussed in Thread: WL1835

Hello,

I'm doing a project to port the MCP8.4 driver to a new processor and FreeRTOS OS.

I have got the firmware to be loaded and all initialisation to complete successfully. To continue the porting I have continued to integrate wpa_supplicant.

I have come as far as to scan for AP's and initiate the association.

My problem is that during the association when the driver is to request an authentication there is a TX problem reported. I have logged both in driver and in the WL1835 firmware. logfiles are attached. Below I have extracted the area in the logs where I have identified the problem.

Any ideas what could be the problem?

    Hi,

    I don't see any attachment.
    Can you attach it again?

    Gigi,

    I do'nt find the attach button or how to attach. The file is long so do not want to copy it into the post.

    Hi Magnus,

    If you select "Use rich formatting", then there should be an option to attach...

    Hi Magnus,

    First, I see several issues in the Driver logs (not sure if fully related to the issue):

         : 2174.075594: ConfSeq                 , WARNINGconfigTemplateFrameSize: Frame size (=514) of CmdType (=14) is bigger than MAX_TEMPLATES_SIZE(=512) !!!

         : 2175.497346: roleSta               , WARNINGgetMaxRate: No rate was found, mask is 0x0

         : 2193.272247: qosMngr                 , WARNINGupdateIEinfo-> trying to update qos paramters without active protocol !!!roleSta 

    : 2193.267537: mlmeParser , INFORMATIONMLME_PARSER: unknown IE found (51)
    : 2193.268034: mlmeParser , INFORMATIONMLME_PARSER: unknown IE found (51)
    : 2193.268546: mlmeParser , INFORMATIONMLME_PARSER: unknown IE found (74)
    : 2193.269045: mlmeParser , INFORMATIONMLME_PARSER: unknown IE found (127)
    : 2193.269553: mlmeParser , INFORMATIONMLME_PARSER: unknown IE found (11)

    But, eventually, I see disconnect as the device RX Buffers are full (from WLAN FW side):

    Rx Table Full!!!

    This leads to drop of frames (and beacons) until disconnection

    Raising BSS Loss event. role: 1

    (but I do not see that in the driver side)

    possible issues:

    1 - Miss of interrupts in the host side 

    2 - Too slow CPU or handle of interrupts

    3 - One of the above issues (section 1) is problematic
