Tool/software: TI-RTOS

I need your help with internal flash memory mapping of cc1310 launchpad.

i have some confusion regarding internal flash memory mapping.

1: Internal flash size is of cc1300 launchpad is 128kb but my file size is 131kb, but still using uniflash i am able to flash the image on internal flash and it works fine. how?

2: In .hex file i can see there are some address are mention before every data. what are those address and how they are resolve by launchpad.

3: what is maximum slot size should i use in external flash as size of firmware is variable. currently i am using slot size is 128kb which is equal to internal flash size of cc13-90. and found that image with metadata size will be around 132-133kb and with bootloader size is around 246kb for current firmware.

Hi,

1. Are you sure that your image is 131kb? Please take a look in your .map file to see how big your flash image is.
2. Please take look here: en.wikipedia.org/.../Intel_HEX for details on a .hex file
3. Max size on internal flash of CC1310 is 128kb.

Best Regards,
R.M

and compile using "make -j4 TARGET=srf06-cc26xx BOARD=launchpad/cc1310". command.

Hi,

Your file size is in kbit and uses metric prefix (131.072 * 1000 = 131072 bits) while the flash size is in binary prefix (128 * 1024 = 131072 bits) so your image file contains an flash image with size 128KB and will fit on a CC1310.
