MMWCAS-RF-EVM: MSS ESM Fault for AWR1243P

MMWCAS-RF-EVM: MMWCAS-RF-EVM: MSS ESM Fault

Hi,Kaushal Kukkar

I read following thread

https://e2e.ti.com/support/sensors/f/sensors-forum/896224/mmwcas-rf-evm-mss-esm-fault-for-awr1243p?tisearch=e2e-sitesearch&keymatch=MSS%25252520ESM%25252520Fault%25252520error%25252520status%25252520Async%25252520event%25252520recieved%252525E3%25252580%25252580%252525280x400000%2525252C%252525200x0%25252529#

Please teach me about detail of MSS ESM Fault Error.

Does "MSS ESM Fault error status Async event recieved (0x400000, 0x0)" occur every frame?
If I set  number of frame to 1000, up to number of 1000 "MSS ESM Fault error status Async event
recieved (0x400000, 0x0)" occur at one device.
Is my understanding correct?

    Hello User,

    As Kaushal mentioned, ESM fault indicates frame clock failure. In cascade mode, you need to have DIG_SYNCOUT of master routed on PCB and connected to both slave and back to Master DIG_SYNCIN. This DIG_SYNCIN triggers the frame clock and if this is not done or has jitter, you could see the failure.

    Can you confirm your dig_sync connections are proper? Also, it would be good if you could send us your board schematics. This way it's easier for us to debug. (I've already asked for your board schematics on a couple of other threads as well)

    Regards,

    Ishita

    Hi Ishita
    Thank you reply.

    I will send information about schematics by email.

    please tell me your email adress.

    Hello User,

    Since you told us that you're a customer of Takashi Onawa, would it be possible if you could send him the designs directly and then he can send those to us.

    I won't be able to share my ID on a public forum.

    Apologies if I caused you any inconvenience.

    Regards,

    Ishita
