DCA1000EVM: commands field description

Hi Spring,

I've asked a DCA1000EVM expert to look into your query and someone should have an answer for you sometime next week.


Cheers,

Hi Akash,
Any news on the issue? While I have found out the meaning of some fields (a little bit of rev-eng) I'd prefer an official answer. If you could supply the payload description for all commands it would be even better.

The schematics would also be very handy.

Thanks.

Hi,

We are in the process of getting DCA1000 schematics on ti.com. Will keep you posted on that.
As for the commands, sorry we can not share the document as it was done by third party.
The values of CONFIG_PACKET_DATA_CMD_CODE and CONFIG_FPGA_GEN_CMD_CODE are provide in DCA1000 user guide.
Examples using the command code is in table 13 and 14 where the command code RESET_FPGA_CMD_CODE was used as an example (value 0x01).

Hope that helps. Currently capture raw data without mmwave sutdio is not supported.

Thanks and Regards,
Michelle

Hi Michelle,

looking forward for the schematics.

Regarding the command description. The "Command code" field is documented properly in table 12 of SPRUIJ4. What is undocumented is "Data" field for the commands, except the reset command (RESET_FPGA_CMD_CODE), which does not have a data field (i.e. "Data size" field is zero). What I'm looking for is something like Table 13, but for commands other than reset.

Thanks.

Hi,

Schematics can be downloaded under DCA1000 website- design files. Here's the direct link:
www.ti.com/.../sprr350

For DCA1000, our current support is limited to mmwave studio related only. Sorry about it.

Regards,
Michelle
