Hi Ti Folks,

Well to test this LTE20MHz 8xlink cpri data & vendor specific test code.

4113.LTE_Cpri_CW_Test.c

Data sent and received completed.

Vendor Specific not completed.

Part is set to control word test. # ifdef CW_TEST.

TX happens once and RX should not take wrong.

What am I doing wrong? Me check my code, I'm sorry, but I'll ask.

You have lte multicore navigator version with Tx / Rx vendor specific test code.

Thanks,

gyosun

Hi,

unfortunately, our hyperframe boundary delimiter has a physical level issue about timing, so we do not recommand to use this option for your application. Please use NULL delimiter or 4B5B encoding, instead of Hyperframe delimiter. Let me know if those options still doesn't make your application work.

Regards,

Albert

Hi Albert,

I saw you try, the result is the same.

And what is wrong?

Thanks,

I can not tell you the design detail. simply say, PE could not catch the exact start fetching point of data, so the first packet couldn't be inserted from the real Hyperframe boundary correctly.
