IWR6843: Include Additional Binary into a Metaimage

Curtis Belknap

Part Number: IWR6843

I have a custom carrier board that hosts an IWR6843 in addition to an FPGA for consuming the LVDS stream. I would like to supply a monolithic binary image that contains the image for the radar processor in addition to the FPGA bitstream. The idea is that the radar configures the FPGA on power-up with a bitstream pulled from the QSPI SFLASH.

Is it possible to use the TI image generation tools to incorporate an arbitrary binary file into the radar metaimage?

If it is not possible, could I use one of the other metaimage slots (e.g. 3 or 4) to store the binary in the QSPI SFLASH?

I would like to avoid multiple steps to program the SFLASH; packaging the two binaries (radar metaimage and FPGA bitstream) together then loading in one operation is highly desirable.

Cheers,

Curtis

Hello

Have your tried using the last step in image generation to modify it and include more more binary.

You may have to check the image gen protocol to understand how the offsets are provided and what format the binary needs to be in.

Please take a look at the Bootloader document under the Technical Docs/App notes of the Product/Device page on ti.com.

Thank you,

Vaibhav

If I understand correctly, append the bitstream to the end of the radar binary image after the image CRC? Then use the QSPI driver to read the flash after the radar binary image + CRC?

If so, this should be pretty straightforward to implement.

Curtis,

I believe this should be correct. Putting it after the CRC should ensure it's not loaded by the bootloader. Give it a shot and let me know if you have any further questions.

Best Regards,
Alec
