CCS/LAUNCHXL-CC2640R2: OAD flash error after add a new task in Simple_Peripheral

Part Number: LAUNCHXL-CC2640R2

Tool/software: Code Composer Studio

Hi,

I'm trying to add a new task in simple_peripheral_oad_offchip example to control LED at differente BLE connection status, using mailbox to pass command.

But after add this task, the OAD will fail and return OAD_FLASH_ERROR.

Is there anyway to check the problem?

Using CCS the latest version and SDK version is simplelink_cc2640r2_sdk_3_20_00_21.

If there is more information need to provide, please let me know.

BTW, I tried to add uartlog to simple_peripheral example, and it will become very hard to discover UUID by btool, also, the OAD process will timeout at the first WriteImageBlock.

Is there conflict between uartlog and the example?

Thanks.

Hi,

Update.

The issue cause by the flash CS pin was modified to another usage, so the OAD_FLASH_ERROR will occur.

But there's a problem is that during OAD update, SimplePeripheral_processStackMsg will receive an error code "HCI_BLE_HARDWARE_ERROR_EVENT_CODE".

Please help for this issue.

Thanks.

Hi Curly,

Are you using on- or off-chip OAD?

Are you using the BLE or BLE5 stack?

Thanks,
Elin

Hi Curly,

Okay, have you tried doing a "minimal OAD" i.e. just changing the version number on the image to see if the actual OAD works?

Thanks,
Elin

Hi Elin,

I tried only modified the version in oad_image_header.h, and it works in aoriginal simple_peripheral_oad_offchip example.

Thanks.

Hi Curly,

Thanks for verifying.

How much bigger is the image after you have added the LED task?

Thanks,
Elin

Hi Elin,

The *_oad.bin is about 70KB, but I fount that if I changed the optimization level to 4, this problem was solved, code size is reduced to 54KB.

Thanks.

Hi Curly,

I'm glad you were able to fix your problem. Changing the optimization level can have a significant effect on the code size.

I believe you should increase them all.

Thanks,
Elin
