CC1312R7: A compilation error occurred when the SPIFFS related function was called

Part Number: CC1312R7
Other Parts Discussed in Thread: SYSBIOS, SYSCONFIG

Hi Team TI,

Recently I downloaded the official latest SDK development kit: simplelink_cc13xx_cc26xx_sdk_7_40_00_77, I plan to add file system SPIFFS related operations in the ns_coap_oad_offchip_LP_CC1312R7_tirtos7_ticlang project, I looked at the routine spiffsexternal_LP_CC1312R7_tirtos7_ticlang and ported the related functions to the ns_coap_oad_offchip project. I called the SPIFFSNVS_config() function in mainThread and found that it did not pass at compile time. The undefined identifier ti_sysbios_gates_GateMutex_create appeared. Then, after I changed ns_coap_oad_offchip-sysconfig-BIOS-Runtime Support Library Lock Type-GateMutexPri to GateMutex, the compilation was normal. May I ask what is the reason for this, why the function related to SPIFFS is called, and the compilation error is reported?

    Hi Bill,

    If you are asking why you are seeing the error when calling SPIFFSNVS_config(), it is because:

    • This function calls MutexP_create() which in turn calls GateMutex_create(). 
    • And if you are using TIRTOS 7, the GateMutex_create function is defined as ti_sysbios_gates_GateMutex_create in GateMutex_defs.h. 
    • For GateMutex_create to be defined, you would need the selection in Sysconfig. 

    Regards,

    Sid

    Hi,Sid

    Thanks for your answer. Based on your response, I assume that if SPIFFSNVS_config() is called, then sysconfig-BIOS-Runtime Support Library Lock Type must be set to GateMutex, right?

    Yes, you are right
