Device & Configuration affected

• CC2340R5
• Onchip & Offchip OAD

• Fail Reproducibility 100% 

Steps to reproduce

1. After creating a connection with the CC2340R5
2. Start OAD 
3. Click Cancel
4. Click Send again
5. Device disconnect and OAD Fails

Workaround:

Behavior is occuring due to the double use of flash_init(). For a workaround, the implementation of the following functions must be replaced in this file source\ti\bleapp\util\sw_updatesw_update.c

Status_t SwUpdate_Open(swUpdateSource_e source)
{
Status_t status = SUCCESS;

if(NULL == pSwUpdateModuleGlobalData)
{
pSwUpdateModuleGlobalData = (swUpdateModuleGlobalData_t *)ICall_malloc(sizeof(swUpdateModuleGlobalData_t));
// Initialize the flash interface
flash_init();
if(NULL == pSwUpdateModuleGlobalData)

{ return(FAILURE); }

}

// This variable controls whether the OAD module uses internal or external flash memory
pSwUpdateModuleGlobalData->pageSize = hasExternalFlash()?EFL_PAGE_SIZE:INTFLASH_PAGE_SIZE;
pSwUpdateModuleGlobalData->pageMask = hasExternalFlash()?(~EXTFLASH_PAGE_MASK): (~INTFLASH_PAGE_MASK);

status = flash_open();
if(status != FLASH_OPEN)

{ return(NV_OPER_FAILED); }

status = readFlash(HDR_OFFSET, (uint8_t *)&(pSwUpdateModuleGlobalData->primaryHdr),sizeof(pSwUpdateModuleGlobalData->primaryHdr));

return (status);
}

And

void SwUpdate_Close(void)

{ flash_close(); }
