Part Number: AWR1243BOOST
Other Parts Discussed in Thread: AWR1243, MMWAVE-DFP

To whom it may concern,

Based on the "swra574.pdf(AWR1243 Cascade)", I want to set  enabling "OSC_CLKOUT" by modifying mmwavelink_example. Please show how to modify the source code (mmw_example.c).

    Hello,
    Current mmWave-DFP example doesn't support cascade mode of AWR1243.

    Although in general to work with cascade AWR1243 (master+slave), Host needs to invoke 'rlSetChannelConfig' command to master AWR1243 with 'rlChanCfg_t->cascading' set to 0x0001 (MULTICHIP_MASTER). After receiving this API, Master AWR1243 device will start generating OSC_CLKOUT.

    Further could you please explain your hardware setup for cascade, it'll help us to give more focused suggestions.

    Hello,

    Thank you very much for giving the advice. I can start generating OSC_CLKOUT by modifying mmw_example.c.

    I added the below command :

      rfChanCfgArgs.cascading = 0x0001

    at line 748 of mmw_example.c (Ver. 00_09?01_06)

    Best regards.
