Hi
I am having some issues with running QSPI on the nRF5340DK board.
After I disabled the QSPI, I found the board still having a high current consumption of 700 uA.
Although I tried trying edit source code follow the nrf52840_errata [122] docs which had a similar problem. But I still can't fix the problem.
static int qspi_nor_read(const struct device *dev, off_t addr, void *dest,
size_t size)
{
if (!dest) {
return -EINVAL;
}
/* read size must be non-zero */
if (!size) {
return 0;
}
const struct qspi_nor_config *params = dev->config;
/* affected region should be within device */
if (addr < 0 ||
(addr + size) > params->size) {
LOG_ERR("read error: address or size "
"exceeds expected values."
"Addr: 0x%lx size %zu", (long)addr, size);
return -EINVAL;
}
int rc = ANOMALY_122_INIT(dev);
if (rc != 0) {
goto out;
}
qspi_lock(dev);
nrfx_err_t res = read_non_aligned(dev, addr, dest, size);
qspi_unlock(dev);
rc = qspi_get_zephyr_ret_code(res);
out:
ANOMALY_122_UNINIT(dev);
return rc;
}
static void anomaly_122_uninit(const struct device *dev)
{
struct qspi_nor_data *dev_data = get_dev_data(dev);
bool last = true;
qspi_lock(dev);
#ifdef CONFIG_MULTITHREADING
/* The last thread to finish using the driver uninit the QSPI */
(void) k_sem_take(&dev_data->count, K_NO_WAIT);
last = (k_sem_count_get(&dev_data->count) == 0);
#endif
if (last) {
while (nrfx_qspi_mem_busy_check() != NRFX_SUCCESS) {
k_msleep(50);
}
nrf_gpio_cfg_output(QSPI_PROP_AT(csn_pins, 0));
nrf_gpio_pin_set(QSPI_PROP_AT(csn_pins, 0));
//*(volatile uint32_t *)0x40029010ul = 1ul;
//*(volatile uint32_t *)0x40029054ul = 1ul;
nrfx_qspi_uninit();
qspi_initialized = false;
}
qspi_unlock(dev);
LOG_INF("anomaly_122_uninit");
}
