In program using flash DA14531MOD missing P25Q11U_DEV_INDEX

I am trying to read/write configuration data to the flash in my program. The configuration data is a 512 uint16_t array. I am following the "Using SDK6 Peripheral Drivers" doc. I tried to change the flash configuration to the on-board P25Q11U device on-board the module. The P25Q11U_DEV_INDEX is missing from the enum in spi_flash.h of known devices.

I have included spi_flash.c and spi_531.c drivers.

Is there a specific 14531MOD example or documentation I can follow or a different driver I am missing?

Thank you,

Larry

我跟inued assuming the P25q11u is the same as the P25Q10U, I get the SPI_FLASH_ERR_WEL_ERROR error when I try a flash errase.

I also tried:

static const spi_flash_cfg_t spi_flash_cfg = {
.dev_index = P25Q10U_DEV_INDEX,
.jedec_id = P25Q11U_JEDEC_ID,
.chip_size = P25Q11U_CHIP_SIZE,
};

I added the following as recommended by the "DA14585/586 interfacing with external memory" application note for P25Q10U.

spi_set_bitmode(SPI_MODE_8BIT);
spi_transaction(0x06); //Write enable
spi_set_bitmode (SPI_MODE_16BIT);
//Write 00 to the status register, this disables all memory protection bits
spi_transaction(0x01 << 8);

Still the same error.

Thanks,

Larry

Hi lecarter190,

Hi lecarter190,

Thanks for your question. Please check out the SPI Flash SDK example : 6.0.14.1114\projects\target_apps\peripheral_examples\spi\spi_flash

This example aims to demonstrate how to perform the basic read/write functionalities. Just build the Keil project for DA14531 configuration and program the module. Additionally, the example sis using the UART ( UTX on P06), so place a jumper on J1.UTX to see the logging info on a serial terminal. The P25Q10U_DEV_INDEX is added on known_spi_devs_list[] structure and it is OK to interact with the on-module flash.

Thanks, PM_Dialog

Thanks,

The example does work, I will go thru it and see what I am missing in my code. I still don't see the Index for the 11U chip, but it works as coded.

Again,

Thanks

Got it, I am using the DA14531MOD and forgot to Reserve and GPIO_Configure the internal pins to the flash. Out of sight, out of mind.

Again,

Thanks
