TM4C129CNCPDT: Need bare minimum code/reference for downloading the image/file from UART to SPI Flash

VINOTH KUMAR RK

Part Number: TM4C129CNCPDT

Hi,

A new feature required where the requested file from laptop should be taken from UART (which is connected with laptop) and copy it to SPI Flash device (using 512Mb flash)
- http://www.mouser.com/ds/2/591/cfg_cf52012-472605.pdf

We need some good reference for the same. Please help.

Note: We're not using any RTOS or OS.

Regards,

Vinoth

I can't seem to understand the request.

Do you want to copy data from a laptop into a SPI flash IC, using as the controller a TM4C129 which is connected to the laptop via UART?

Are you already able to write anything to the said Flash device? Check SPI Tivaware examples.

Are you already able to transfer anything via UART? Check UART Tivaware examples.

Regards.

Hello Vinoth

For using an external SPI Flash refer to the following example codes in the TI Reference Design
