IWR6843: About the SPI bootloader of IWR6843

Hui Chen

Part Number: IWR6843

Hi Ti experts,

I want to design a new application with IWR6843 and STM32F103 MCU. The topology of this new design is that connect the MCU SPI interface to IWR6843’s SPI interface, meanwhile keep the QSPI interface from connecting to a QSPI FLASH, so the bootloader of IWR6843 master subsystem will load user’s firmware from the SPI path connected to MCU. Is there any demo or example of this application available? I want to know the more details of the data exchanging at SPI bus, could you give me some advices?

Hello,

Have you been able to look at the SBL example provided as part of the mmWave SDK?

Thank you,

Hi,

You can refer to UART SBL @ C:\ti\mmwave_sdk_03_05_00_04\packages\ti\utils\sbl

and SPI SBL @C:\ti\mmwave_industrial_toolbox_4_6_0\labs\common\src\utils\sbl

Thanks

Thanks for your reply. But I still can't find the SPI SBL in the link in your last post.

I have clicked open all of the folders in the mmwave sensors folder, however I can't find the folder named "common", I also use the searching function of this website to search for SBL/SPI/common and so on, but I can't find any useful result.

Could you help kindly double check the location of the SPI SBL? It is very important for us to achieve our feature of product. :)
