IWR1642BOOST: can IWR1642Boot output data to spi output

Hi Terry,

Yes, you should be able to send data to SPI. Please refer to SPI test code in SDK for the same.

Thanks

Hi Yogesh

could you please tell me the file name so that i can search ?  is this test code for reading data from SPI ? or actually maksing the change to send data to SPI bus ?

Thanks

Hi Terry,

Both. See ~\mmwave_sdk_xx_xx_xx_xx\packages\ti\drivers\spi\test\xwr16xx\main.c

Thanks

Yogesh

Hi Yogesh,

Thanks a lot, I found this file . I am still trying to get the big picture.   the board is connected to pc.  by default it sends day throught UART right ?

and this test code running on host pc  to read data from the platform ? 

Thanks,

Terry

Hi Yogesh,

Is there a document which describe how do i build this test code ? mmwave_sdk_xx_xx_xx_xx\packages\ti\drivers\spi\test\xwr16xx\main.c

Thanks,

Terry

Hi Yogesh,

I followed the mmwave_sdk_unit_test_procedure.pdf.  first use ccs to load  ti/mmwave_sdk_03_03_00_03/packages/ti/drivers/spi/test/xwr16xx/xwr16xx_spi_mss.xer4f first . I would like to follow 1. 6. R4 SPI/FTDI Test.

On xwr16xx side I change the variable as following

Parameter

Value
gXWR1xxxLoopbackTest 0
gXWR1xxxMasterWithXWR1xxx 0
gXWR1xxxSlaveWithXWR1xxx 0
gXWR1xxxSlaveWithFTDITest 1

on my host ubuntu pc . 

1.I went to  ti/mmwave_sdk_03_03_00_03/packages/ti/drivers/spi/test/unix

2. I followed READ me in above directory and installed D2XX driver the latest 1.4.8 version it is .gz file i can not exact it. so i downloaded 1.4.6 for x64 (64bit) then compile this spiTest sucessfully

3. when I run it on my pc i need provide VID and PID . i am not sure which one to give so  i did lsusb first . it prints 

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0cf3:e301 Atheros Communications, Inc.
Bus 001 Device 036: ID 0c45:7692 Microdia
Bus 001 Device 035: ID 22d4:2100
Bus 001 Device 034: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 054: ID 0451:bef3 Texas Instruments, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

so i run like this on pc sudo ./spitest 0x0451 0xb3f3  on pc side it prints err like 

Incorrect Message received from slave: magic =0x2946, dataLen=0, seqNo=9485
Error, couldn't send command to MSPEE
Incorrect Message received from slave: magic =0x2946, dataLen=0, seqNo=9485

Error, couldn't send command to MSPEE
Incorrect Message received from slave: magic =0x2946, dataLen=0, seqNo=9485

then when I run ccs to run the xwr16xx it seems test is selftest and did not wati for host pc to send cmd

btw i only connect iwr1642boost board to pc via usb. there is no dev pack add-on board

it looks like in order to run ti/mmwave_sdk_03_03_00_03/packages/ti/drivers/spi/test/unix on host pc i need put on devpack board on top of iwr16xx. 

then the test seems okay ?

Terry,

Thanks for confirming. I will mark it as closed
