Hello Community,

i will open a new Post due to it seems to be a different Task.

Original Post came from here:

https://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/639263

in Case i transmit the Byte Combination 0x0F and 0x3D the Byte 0x3d is received as 0x00.

i tried with 0x0E 0x3d and with 0x0F 0x2D in this cases all Bytes are received Correctly.

Do i have a missunderstanding in alignment or is this a special Combination which the stack will interpret in the false way?

Many Thanks in advance for any answers

Best Regards

Martin

Hi,

I am not aware of any data pattern dependence of the NDK. What test application you used for testing? Is the NIMU_emacExample_EVMC6657C66BiosExampleProject? did you run it with CCS/JTAG at no-boot mode? Do you have any packet sniffer at the EMAC port to make sure the incoming packet pattern?

Regards, Eric

Hi Eric,
I have a modified Dataserver Example in usage.
Dip-Switches are set to No-Boot.
I saw with WireShark the correct Data.
Thats why i am so confused.
But if there are no data pattern depencies .... it must be elsewhere....
Thank you Eric
