IWR1443: Bootloader over SPI or UART

Hello Akash,

Thanks for the reference link, but I already pointed to a thread where you mentioned it and it is limited to SPI communication only.

Our requirement is example bootloader for IWR1443 over SPI or any other serial protocol. 

Thanks and regards,

Hi Nick,

Yes, your statement is right about my query!

In the section 6.8.2 of IWR1443 datasheet it is mentioned that ,

"If a valid image (or the QSPI Serial Flash is not found), the bootloader initializes the SPI port and awaits
for the image transfer. This operation comes handy for configurations where the IWR1443 is interfaced to
an external processor which has its own nonvolatile storage hence can store the user application and the
IWR1443 device’s firmware image."

My query is for application note supporting above statement from TI, with a example utility or firmware for external processor which loads User Application and Radar Patch to IWR over SPI.

Atul,

Within the Radar SDK:

check this is reference implementation for SPI bootloading: pdk\packages\ti\drv\vps\src\devices\radar_ar12xx\src\bspdrv_ar12xxFmwPriv.c

Best,

Nick

Atul,

The overall SPI boot mode and sequence is described in section "2.3 Bootmode – SPI" of the Bootloader Flow app note at: www.ti.com/.../swra561.pdf. The SPI protocol and APIs used during the download are described in the AWR1xxx Radar Interface Control Document in the DFP package docs directory (DFP is installed as part of Radar SDK mentioned below or can be downloaded separately from: www.ti.com/.../mmwave-dfp). The main download API is described in section "10.1.4 rlDeviceFileDownload".

As a code reference, the Radar SDK mentioned previously (actually named PROCESSOR-SDK-RADAR) can be downloaded from the following link.
www.ti.com/.../PROCESSOR-SDK-TDAX

And the full path to the file mentioned previously (after installing PROCESSOR-SDK-RADAR) is:
<RadarSDK>\ti_components\drivers\pdk_01_09_00_17\packages\ti\drv\vps\src\devices\radar_ar12xx\src\bspdrv_ar12xxFmwPriv.c

This file contains a function named Bsp_ar12xxFmwSpiDwld() which downloads the three required images (BSS, MSS, Config (mem_swap)). If you look at the code you will see it eventually calls the mmWavelink API rlDeviceFileDownload() function from the mmWave DFP package (included with the PROCESSOR-SDK-RADAR install). This function is found in the source code at <RadarSDK>\ti_components\radar\mmwave_dfp_01_00_00_01\ti\control\mmwavelink\src\rl_device.c and is described in the DFP mmwavelink Doxygen at:<RadarSDK>/ti_components/radar/mmwave_dfp_01_00_00_01/ti/control/mmwavelink/docs/doxygen/html/group___device.html

Please mark the thread as answered if the question is resolved or reply if more support is required.

Best Regards,

John,

Thank You!

Since you bookmarked the post with IWR1443, I assue the information is equally applicable for bootloading of IWR1443.  I will definitely look into it.

One quick query, does the example contains code reference for SPI master at other end may be a MSP32 or TIVA ARMCM4F? Is there any?

Thanks and regards,

Atul

Hi

In the SWRA561 document it is written that booting from sflash is for development phase only.
In the deployment phase you need to use the SPI boot.
Given that I will have to use a very small controller to obtain the distance measured by the IWR1443 and that it is unthinkable for this controller to load via SPI the firmware at each power on since the product will be used in ON/OFF mode and the final consumption will have to be <3.5mA, can I think of using the boot from QFLASH also on the production boards?
To do this, how can I connect UNIFLASH to the IWR? Do I have to go through the XDS110?
Thanks Nino
