IWR6843ISK: boot-up problem

Part Number: IWR6843ISK


Hi, we could hardly boot-up IWR6843ISK.

We have upgraded from SDK 3.0.0.6 to SDK 3.0.0.8, the problem remains. 

According to “mmWaveICBoost and Antenna Module.pdf”

3.1.1 Power connections
The Industrial Starter Kit is powered by the 3.3V from the 60-pin HD connectors. As soon as the power is
supplied, on board PMIC and LDO will generate the voltages. PGOOD LED will glow indicating all voltage
rails are in limits
NOTE: After the 3.3 V supply is provided to the EVM, it is recommended that NRST signal to be
toggled once to ensure a reliable boot-up state and this signal is accessible on 60-pin HD
connector。

Using RESET key can boot-up sometimes, but fails most of times.

Can we test the boards somewhere?

  • Hi,

    Sorry to hear about the problem on your setup. In order for us to debug the issue, could you please follow the instructions below and provide a CCS stack trace for the OOB demo at initialization?

    1. Follow the instructions provided in section 3.2.2: CCS development mode, to run the OOB demo in CCS mode. Please use the pre-compiled binary  Cortex R4F binary under C:\ti\mmwave_sdk_03_00_00_08\packages\ti\demo\xwr68xx\mmw\xwr68xx_mmw_demo_mss.xer4f. Note that the 68xx SD OOB demo does not require the DSP so you can leave the DSP unconnected in CCS.

    You should see output similar to the following in the CCS console:

    2. Halt the R4F core using the pause button in the CCS toolbar and take a snapshot of the function call trace as shown below. Please provide the call trace snapshot from your EVM for the failure condition.
