 How can we troubleshoot the problem? Thanks.

    Hi Wang,

    The basic reason for the checksum error is the discrepancy in the transmitted data. Have you tried the same with any other sample? are you facing the similar issue every time?  Also, can you confirm once if you are still using the same part number which is mentioned in the previous thread? Meanwhile, let me check with the team if they've got any update on the previous thread issue.

    Regards,

    Shruti

    Hi,shruti

    In the following picture, I grab the interrupt signal on the oscilloscope, and the interrupt signal is not normal. First sending CNYS can generate falling edge,but second writing CNYS can't generate falling edge. The interrupt signal doesn't go down until one second.

     How can we troubleshoot the problem?  which callback function  trouble the problem ?  sem or HostIrq ？Thanks.

    Regards,

    Rui

    blue is spi irq signal, yellow is spi clock signal.

    Hi Rui,

    Can you perform the same test with some other board and see if you are facing the similar issue?

    Hi shruti,

    I have tried another custom board but the result is the same.

    Hi Rui, 

    I have checked with the team regarding your issue. Based on your current thread and the one that you have attached in this e2e, it looks like the sample you have for 2243, doesn't support cascade feature.

    Hi shruti,

    I use mmwcas-rf-evm and custom board by myself. The project is mmWaveLink_singleChip_example on linux.

    Hi Rui,

    Can you share the similar information about the device which has been shared in the attached thread such as the part number, error number after sending the ChannelConfig API call to the Master device etc, and have you tried the same experiments on the device which has been discussed in attached thread if yes, then please provide your observations?

    Regards,
