Hi Guys,
I'm interested to get guideline on how could I customized the qspi example from nordic in terms of pins and command. I don't see any different between MX25R6435F vs S25FL064L chipset
I was trying to change the qspi example code and unsuccessful control the qspi using the following setting.
#define QSPI_CSN NRF_GPIO_PIN_MAP(0,19) #define QSPI_IO0 NRF_GPIO_PIN_MAP(0,21) #define QSPI_IO1 NRF_GPIO_PIN_MAP(0,20) #define QSPI_IO2 NRF_GPIO_PIN_MAP(0,22) #define QSPI_IO3 NRF_GPIO_PIN_MAP(0,24) #define QSPI_SCK NRF_GPIO_PIN_MAP(1,0)
And the I did some change to some of the header as below
nrfx_qspi.h
#define NRFX_QSPI_DEFAULT_CONFIG \
{ \
.xip_offset = NRFX_QSPI_CONFIG_XIP_OFFSET, \
.pins = { \
.sck_pin = QSPI_PIN_SCK, \
.csn_pin = QSPI_PIN_CSN, \
.io0_pin = QSPI_PIN_IO0, \
.io1_pin = QSPI_PIN_IO1, \
.io2_pin = QSPI_PIN_IO2, \
.io3_pin = QSPI_PIN_IO3, \
}, \
.irq_priority = (uint8_t)NRFX_QSPI_CONFIG_IRQ_PRIORITY, \
.prot_if = { \
.readoc = (nrf_qspi_readoc_t)NRFX_QSPI_CONFIG_READOC, \
.writeoc = (nrf_qspi_writeoc_t)NRFX_QSPI_CONFIG_WRITEOC, \
.addrmode = (nrf_qspi_addrmode_t)NRFX_QSPI_CONFIG_ADDRMODE, \
.dpmconfig = false, \
}, \
.phy_if = { \
.sck_freq = (nrf_qspi_frequency_t)NRFX_QSPI_CONFIG_FREQUENCY, \
.sck_delay = (uint8_t)NRFX_QSPI_CONFIG_SCK_DELAY, \
.spi_mode = (nrf_qspi_spi_mode_t)NRFX_QSPI_CONFIG_MODE, \
.dpmen = false \
}, \
}
nrf_drv_qspi.h

Target memory chip to use.
