CCS/LAUNCHXL-CC1312R1: keep nvs internal data when upgrade via UART bootloader

Tool/software: Code Composer Studio

Hi,

I use

./host_cc13xx-sbl /dev/ttyS1 file.bin cc13x2 -e -p -v

for firmware upgrade. It erases all data. Can I keep nvs internal data after upgrde?

I use C:\ti\simplelink_cc13x2_26x2_sdk_2_40_00_81\examples\rtos\CC1312R1_LAUNCHXL\drivers\nvsexternal for saving my data.

Thank you.

Hi Chris,

You do not have to write to the entire flash, but you need to use a hex file instead of a binary image. This would let you keep your NVS flash page(s).

More details here: www.ti.com/.../swra466 and in the Technical Reference Manual.

Regards,
Fredrik

Hi Fredrik,

How to generate hex file? I can only generate bin file using the below command:

"${CCE_INSTALL_ROOT}/utils/tiobj2bin/tiobj2bin.bat" "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.bin" "${CG_TOOL_ROOT}/bin/armofd.exe" "${CG_TOOL_ROOT}/bin/armhex.exe" "${CCE_INSTALL_ROOT}/utils/tiobj2bin/mkhex4bin.exe"
