AM2634: QSPI Pin Direction

Dominik Wuest

Part Number: AM2634

I want to share the external flash memory between two devices. For that I need to change the QSPI pins to high-Z in the application.

I have already tried to close the driver by Board_driversClose(), but the CLK and CS are still configured as an output.

Is there an easy way to do this?

Thanks and best regards

Does no one have an idea how to solve this?

Simply call this function - Pinmux_config(cfg, PINMUX_DOMAIN_ID_MAIN);

Refer generated/ti_pinmux_config.c

Provide cfg value as

cfg[] = {

{

PIN_QSPI_CLK,

( PIN_MODE(0) |PIN_FORCE_OUTPUT_DISABLE| PIN_SLEW_RATE_LOW )

{

PIN_QSPI_CSN0,

( PIN_MODE(0) | PIN_FORCE_OUTPUT_DISABLE| PIN_SLEW_RATE_LOW )

{PINMUX_END, PINMUX_END}

};
