[Solved] System_printf() on CC2640R2F

[Solved] System_printf() on CC2640R2F

Here is how to implement System_printf() to write to the console on T.I. CC2640R2F, this is the solution to the unsolved closed issue “CCS/CC2640R2F: Implementation of System_printf()” asked on TIs forum: https://e2e.ti.com/support/tools/ccs/f/81/t/670719. Chang the .cfg file to include SysMin, include the preprocessor XDC references, add the bufSize, remove all references to SysCallback: var SysMin =Continue Reading [Solved] System_printf() on CC2640R2F

CC2640R2F: Secure bootloader for encrypted OTA update

CC2640R2F: Secure bootloader for encrypted OTA update

Development of a secure bootloader for encrypted OTA update via BLE. The bootloader has been developed in C in order to allow the OTA update of the Texas Instrument CC2640R2F, securely with an encrypted firmware image. The client controls the private keys and thanks to encryption techniques it is not possible to disassemble the firmwareContinue Reading CC2640R2F: Secure bootloader for encrypted OTA update

Hands on TI CC2640R2F

This is my first experience with CC2640R2F and also with TI more generally so I thought I’ll write down my feelings after a week as it might be of interest to someone else. Background I should mention that this was my very first time developing with TI, which means most of the comments concern TIContinue Reading Hands on TI CC2640R2F
