[Z-Stack Linux Gateway] initialize fail on MIPS platform

Yellow Huang

Other Parts Discussed in Thread: Z-STACK

hi all,

I have done to sign SLA and got full HA-Gateway source and build for ARM-Based/MIPS-based platform successfully.

But my problem is that NWK daemon(NWKMGR_SRVR_xxx) can't receive any frames from the start_application(main.bin) on the new porting QCA MIPS-based platform.

Can you share any relative porting experiments for me?

Originally, it work fine on QCA ARM-based platform with LITTLE-Endian, but the new QCA MIPS-based platform is BIG-Endian.

Thank you.

    Can you please provide some more information to help diagnose this issue.

    - Are the servers running correctly, i.e. after calling ./zigbeeHAgw do you eventually see:

    ===================================================
    tracking 4 pids, 2061 2074 2100 2113
    when we see something missing we will send a SIGUSR2 to pid 1976

    - After running the start_application do you see a connection in /servers/NpiLnxLog.txt:

    root@beaglebone:/z-stack_linux_gateway_arm_binaries/servers# cat NpiLnxLog.txt

    - Are you running zigbeeHAgw and start_application via a local socket on a MIPS machine, or are you running servers and ARM and Demo Application on MIPS?

    Regards,
    TC.

    hi TC.

    I have resolved this issue.

    The root-cause is two-bytes length endian convert error in QCA MIPS BIG-Endian platform, ex:
    // Length field endianness conversion to little endian
    hdr->lenL = (uint8) len;
    hdr->lenH = (uint8)( len >> 8 );

    I change two byte length field to uint16 and use standard htons()/ntohs() to convert:
    hdr->len = htonl(len);

    Thank you.
