RTOS/LAUNCHXL-CC2640R2: CC2640R2-LAUNCHPADXL: Sharing flash chip select

Tool/software: TI-RTOS

Hi,

I am using the external flash chip select pin (IOID_20) as a GPIO (using the GPIO driver). I would also like to support off-chip OAD updates.

How can I release the pin when an OAD is triggered so that it can be used as the flash chip select instead? (triggering an OAD produces an error).

As a work-around I switched to using the PIN driver and calling PIN_remove(...) when handling the SBP_QUEUE_PING_EVT and detecting a new image.

Hi Evan,

Glad you found a work around!

Did you try calling the release command: software-dl.ti.com/.../_g_p_i_o_c_c26_x_x_8h.html

Or GPIO_setConfig ( software-dl.ti.com/.../_g_p_i_o_8h.html ) and remove it from the table manually - prior to starting the actual call to open the serial flash.

Regards,
Rebel

Hi Rebel, ok thanks, didn't see the release function, that will most likely work.
