The sequence to initialise the flash and mount NXFFS should look like the
following (to be adapted for chip and device):
spi = stm32_spibus_initialize(1);
if (!spi)
{
ferr("ERROR: Failed to initialize SPI port 2\n");
return -ENODEV;
}
mtd = w25_initialize(spi);
if (!mtd)
{
ferr("ERROR: Failed to bind SPI port 2 to the SST 25 FLASH driver\n");
return -ENODEV;
}
ret = nxffs_initialize(mtd);
if (ret < 0)
{
ferr("ERROR: NXFFS initialization failed: %d\n", -ret);
return ret;
}
ret = nx_mount(NULL, "/mnt", "nxffs", 0, NULL);
if (ret < 0)
{
ret = nx_mount(NULL, "/mnt", "nxffs", 0, "forceformat");
if (ret < 0)
{
ferr("ERROR: Failed to mount the FS volume: %d\n", errno);
return ret;
}
}
