6lbr Lite issue on LAUNCHXL-CC2650 + ENC28J60

[chenek]

I can run 6lbr Lite on LAUNCHXL-CC2650 + ENC28J60 (I see UART output and can connect to bbbb::100) first time after I download cetic_6lbr_router.bin to LAUNCHXL-CC2650. However, if I press the reset button on LAUNCHXL-CC2650 or power recycle LAUNCHXL-CC2650, I cannot see 6lbr Lite restarts on LAUNCHXL-CC2650 + ENC28J60. There is no UART output and I cannot connect to bbbb::100. I also test this no srf06-cc2650EM+ENC28J60 and result is the same. Since there is nothing output from UART, it's difficult to debug what happens. Does anyone know how to fix this?

I have the same issure with sensortag. It seems that CC2650 have less internal NVM memory than other platforms, so you need to use external flash to store NVM data. Try to make with CC26XX_NVM=ext

I tried to build using "make CC26XX_NVM=ext TARGET=srf06-cc26xx BOARD=srf06/cc26xx all" but it pops the following link errors:

obj_srf06-cc26xx/cc26xx-ext-nvm.o: In function nvm_data_read': cc26xx-ext-nvm.c:(.text.nvm_data_read+0xe): undefined reference toext_flash_open' cc26xx-ext-nvm.c:(.text.nvm_data_read+0x2e): undefined reference to ext_flash_read' cc26xx-ext-nvm.c:(.text.nvm_data_read+0x34): undefined reference toext_flash_close' cc26xx-ext-nvm.c:(.text.nvm_data_read+0x24): undefined reference to ext_flash_close' obj_srf06-cc26xx/cc26xx-ext-nvm.o: In functionnvm_data_write': cc26xx-ext-nvm.c:(.text.nvm_data_write+0xe): undefined reference to ext_flash_open' cc26xx-ext-nvm.c:(.text.nvm_data_write+0x24): undefined reference toext_flash_erase' cc26xx-ext-nvm.c:(.text.nvm_data_write+0x3a): undefined reference to ext_flash_write' cc26xx-ext-nvm.c:(.text.nvm_data_write+0x50): undefined reference toext_flash_close' collect2: error: ld returned 1 exit status make[2]: *** [cetic-6lbr.elf] Error 1

I think all those ext_flash_xxx are missed in CC26xx 6lbr. How can I fix this?

you can try to change the macro CETIC_6LBR_NVM_SIZE in file cc26xx-int-nvm.c:

define CETIC_6LBR_NVM_SIZE 4096//2048

// We use the penultimate flash page as our nvm

define CETIC_6LBR_NVM_ADDRESS (0x00020000 - (2*CETIC_6LBR_NVM_SIZE))

[chenek]

Yes, changing the macro CETIC_6LBR_NVM_SIZE in file cc26xx-int-nvm.c fixes the issue using internal NV. But, what if I would like to use external flash, how can I fix the build problem?

[mcuxmx]

the board srf06/cc26xx with no external flash if you want use it, you should change the relevant source files and makefile files

Thanks for the hint. I fix the issue by using "make TARGET=srf06-cc26xx BOARD=launchpad/cc2650 all"
