Hi
I am trying to get the SDHC/Disk access with FAT working on the nRF9160 dev platform and Asset_Tracker V1 app
It is shown to be connected on the TRACE connector
so P0.21 to P0.25 and the DBG_CMD going to U1B pin 125 if soldered
So I have bought the correct socket and soldered it down
I am only using the 9140 for this
In the config I turn on SDHC
and I have tried the following code added to the asset_tracker v1 app
#include <fs/fs.h>
#include <ff.h>
#include <disk/disk_access.h>
static FATFS fat_fs;
/* mounting info */
static struct fs_mount_t mp = {
.type = FS_FATFS,
.fs_data = &fat_fs,
};
static const char *disk_mount_pt = "/SD:";
static int lsdir(const char *path)
{
int res;
struct fs_dir_t dirp;
static struct fs_dirent entry;
/* Verify fs_opendir() */
res = fs_opendir(&dirp, path);
if (res) {
printk("Error opening dir %s [%d]\n", path, res);
return res;
}
printk("\nListing dir %s ...\n", path);
for (;;) {
/* Verify fs_readdir() */
res = fs_readdir(&dirp, &entry);
/* entry.name[0] == 0 means end-of-dir */
if (res || entry.name[0] == 0) {
break;
}
if (entry.type == FS_DIR_ENTRY_DIR) {
printk("[DIR ] %s\n", entry.name);
} else {
printk("[FILE] %s (size = %zu)\n",
entry.name, entry.size);
}
}
/* Verify fs_closedir() */
fs_closedir(&dirp);
return res;
}
static void init_disk(void)
{
/* raw disk i/o */
do {
static const char *disk_pdrv = "SD";
uint64_t memory_size_mb;
uint32_t block_count;
uint32_t block_size;
if (disk_access_init(disk_pdrv) != 0) {
LOG_ERR("Storage init ERROR!");
break;
}
if (disk_access_ioctl(disk_pdrv,
DISK_IOCTL_GET_SECTOR_COUNT, &block_count)) {
LOG_ERR("Unable to get sector count");
break;
}
LOG_INF("Block count %u", block_count);
if (disk_access_ioctl(disk_pdrv,
DISK_IOCTL_GET_SECTOR_SIZE, &block_size)) {
LOG_ERR("Unable to get sector size");
break;
}
printk("Sector size %u\n", block_size);
memory_size_mb = (uint64_t)block_count * block_size;
printk("Memory Size(MB) %u\n", (uint32_t)(memory_size_mb >> 20));
} while (0);
mp.mnt_point = disk_mount_pt;
int res = fs_mount(&mp);
if (res == FR_OK) {
printk("Disk mounted.\n");
lsdir(disk_mount_pt);
} else {
printk("Error mounting disk.\n");
}
}
void main(void)
{
LOG_INF("Asset tracker started");
k_work_q_start(&application_work_q, application_stack_area,
K_THREAD_STACK_SIZEOF(application_stack_area),
CONFIG_APPLICATION_WORKQUEUE_PRIORITY);
if (IS_ENABLED(CONFIG_WATCHDOG)) {
watchdog_init_and_start(&application_work_q);
}
#if defined(CONFIG_USE_UI_MODULE)
ui_init(ui_evt_handler);
#endif
#if defined(CONFIG_LWM2M_CARRIER)
k_sem_take(&nrf_modem_lib_initialized, K_FOREVER);
#else
handle_nrf_modem_lib_init_ret();
#endif
//TRY THE DISK
init_disk();
cloud_api_init();
work_init();
............
But I have no luck.
Do I also need to configure a SPI port in hal_nordic? and specify the pins in use somewhere?
Is there a working example of the SDCard socket being used anywhere that I can refer to?
