CC2640R2F: Simple_peripheral OAD pending problem

Michael Qian

Part Number: CC2640R2F

Dear all,

Sdk version: simplelink_cc2640r2_sdk_2_40_00_32

Now I use simple_peripheral_oad_offchip with some addition application level code, when i debug OAD function, I found OAD is pending show as below by Btool(btool is used by cc2640r2_sdk_2_40_00_32 BT5.0 stack).

I search E2E and found this would be the issue to read the external flash,

after I debug the code, i found code goes into below function (ExtFlash.c)

bool ExtFlash_open(void)
{
bool f;

hFlashPin = PIN_open(&pinState, BoardFlashPinTable);

if (hFlashPin == NULL)
{
return false;
}

hFlashPin == NULL and returned!

I don't know why called PIN_open() and it returned NULL to hFlashPin.

Then I do a more test,

I do hFlashPin = PIN_open(&pinState, BoardFlashPinTable) in static void SimplePeripheral_init(void),

hFlashPin != NULL,

Does this mean RAM is ran out during the OAD period and can't assign more RAM to new assignment?

Or any other suggestion for the problem?

Many thanks.

Hi Michael,

Can you specify the changes you made to the application layer?

Also, Please attach the complete BTool log.
