I add it's probe in stmicro.c as follow :
/static const struct stmicro_spi_flash_params stmicro_spi_flash_table[] = {
...
+ {
+ .id = 0xba16,
+ .pages_per_sector = 256,
+ .nr_sectors = 64,
+ .name = "N25Q32",
+ },
...
struct spi_flash *spi_flash_probe_stmicro(struct spi_slave *spi, u8 *
idcode) {
...
+ /* clear BP# bit for locked flash */
+ spi_flash_cmd_write_status(flash, 0);
.../
Then I add the macro definition of CONFIG_SPI_FLASH_STMICRO. I got the flash
was detected :
/U-Boot# sf probe
SF:: Got idcodes
00000000: 20 ba 16 10 00 ....
SF: Detected N25Q32 with page size 64 KiB, total 4 MiB/
Can it prove the drvier is correct?
And when I erase the flash, it never come out error, it seemed erase
correctly :
/SF: erase d8 1 0 0 (20000)
status=0x0
...
SF: erase d8 21 0 0 (220000)
status=0x0
SF: Successfully erased 2228224 bytes @ 0x0/
But I read out the data, it is not 0xff.
