Hi Expert,

My customer's soc has no more uart interface. so, they can only use spi interface to program the cc2340.

Where can I find the SPI bootloader host example? Linux based is better.

Any doc about how to program cc2340 by spi interface?

Any spi tool from Linux can do the test?

Hi Frank,

Please reference the Serial Boot Loader Tool available here: https://github.com/TexasInstruments/ble_examples/tree/simplelink_low_power_f3_sdk-7.40/tools/TI_CC2340_Linux_SBL

As you will notice, this tool is based on UART. This can be changed by altering the content of Source/Linux_Serial.c and replacing the UART/COM port operations by SPI.

I hope this will help,

Best regards,
