AWR1243: Host Interrupt keep on coming

Balaji N

Part Number: AWR1243

Hello All,

Connected the AWR1243 chip with external processor.

From AWR1243 chip, the interrupt is keep on coming. Do not know what is the problem?

The log is:

[DBG ] rlDriverRxHdrRead:1598::do nothing [DBG ] rlDriverValidateHdr:376::rlDriverCalChkSum is successful
[ERR ] rlDriverValidateHdr:382::Checksum validation failed for header

Want to know that SPI configuration is proper for AWR1243 device from processor?

i.e. SPI write and read is working properly. How to confirm this. Any ideas?

The main problem is: SPI write and read. Do not know whether SPI device access is proper from Processor or not.

-Thanks.

    Hello All,

    Here, interrupt goes from AWR1243 device to Host.

    -Thanks.

    Hello All,

    Not using nReset pins to power off and power on from mmwavelink.

    Commented out this code. By default, AWR1243 is in Functional mode.

    Put SOP pins to Functional mode. Yellow LED is glowing in board.

    -Thanks.

    Hello Balaji,

    You need to reset the device via rlDeviceEnable callback of the mmwavelink, in that case mmWaveLink can get to know HostIRQ interrupt and read/process SPI data from AWR device.

    HostIRQ will be high till Host writes CNYS pattern (which is being done by the mmwavelink), meanwhile mmWavelink mask that HostIRQ signal (using rlDeviceMaskHostIrq callback).

    I would suggest you to follow all the mmWaveLInk callbacks and implement those at External Processor.

    Please follow this document file:///C:/ti/mmwave_dfp_01_02_06_03/ti/control/mmwavelink/docs/doxygen/html/index.html#proting_sec (install DFP 1.2.6.3 first).

    On top of that DFP package provides reference application as well for Host implementation.
