IWR6243: Flashing guide specific to IWR6243

Part Number: IWR6243
Other Parts Discussed in Thread: AWR2243, UNIFLASH, AWR1243

We are currently testing a custom board with IWR6243.

For flashing the IWR6243, our main source of information is "AWR2243 bootloader flow". Currently our method of flashing is the following:

use UniFlash (latest), select AWR1243 from the device list (because of this thread, in order to flash a single meta-image)
use xwr62xx_metaImage.bin from IWR6243 DFP (following AWR2243 bootloader flow section 3.1: "In ES3.0, the two images are combined into a single meta-image")
flash the single meta-image.

Is this the correct method to flash the IWR6243 in a testing / production environment ?

How can we check after reboot that it was correctly programmed and boots as it should ? (apart from initiating the control interface via SPI)

Hello,

There is indeed a single meta-image. Are you using a hard-coded configuration file? For when the sensor starts and is chirping, there will be a new LED that blinks indicating chirping. You can also send FW commands over UART.

Best Regards,

Pedrhom

This LED is not included in our design unfortunately.

But we were able to test the method only thanks to SPI commands. We can confirm that this flashing method works, since even after removing SPI meta-image transfer, the reported FW version (via SPI commands) corresponds to the DFP version, and the chip is fully functional.
