Hi,
I'm developing a board with an imx28 processor and I use barebox + linux 2.6.35 for the software.
I try to upload the bootloader from barebox shell with tftp but it doesn't work
barebox@IMX28:/ tftp barebox_ivt.sb /dev/null
could not open /dev/null: No space left on device
boot0 is a partition on a SPI flash memory. I have the same if I try to write the file to /dev/null or /dev/disk0.0 (disk0.0 is the boot partition when I work with an sd card)
I Can write the boort file to the spi flash from linux without problem.
here is the configuration of the memory on barebox :
#define BOOT_FROM_SPI 1
static struct flash_platform_data spi_flash = {
.name = "nor-spi", /* Cdev name, optional */
.type = "m25p32", /* Device type, required for non JEDEC chips */
};
static const struct spi_board_info mx28_misu_spi_board_info[] = {
{
.name = "m25p80",
/*
* we leave this with the lower frequency
* as the ssp unit otherwise locks up
*/
.max_speed_hz = 20000000,
.bus_num = 2,
.chip_select = 0,
.bits_per_word = 8,
.mode = SPI_MODE_0,
.platform_data = &spi_flash,
}
};
...
spi_register_board_info(mx28_misu_spi_board_info,
ARRAY_SIZE(mx28_misu_spi_board_info));
add_generic_device("mxs_spi", 2, NULL, IMX_SSP2_BASE, 0x2000,
IORESOURCE_MEM, NULL);
devfs_add_partition("nor-spi0", 0x000000, 0x200000, DEVFS_PARTITION_FIXED, "boot0");
if (BOOT_FROM_SPI) {
cdev = devfs_add_partition("nor-spi0", 0x200000, 0x200000, DEVFS_PARTITION_FIXED, "env0");
if (IS_ERR(cdev))
pr_err("Cannot create env0 on spi flash\n");
else
pr_info("environment storage is on spi flash\n");
}
else {
ret = envfs_register_partition("disk0", 1);
if (ret != 0)
pr_err("Cannot create the 'env0' persistent "
"environment storage (%d)\n", ret);
}
Is there someone who can help me ?
Best regards.
