Hi folks,
I tried to flash some new Atmel/Adesto SPI 512k flash chips with
flashrom0.9.9-rc1-r1942 on Linux 4.15.0-50-generic (x86_64) (from
repositories in linux mint 18.3) and flashrom v1.0.1 on Linux
4.15.0-50-generic (x86_64) (compiled it from source).
Both versions could not find the chip:
-------------------------------------------------------------------------------------
Found Atmel flash chip "unknown Atmel SPI chip" (0 kB, SPI).
This flash part has status NOT WORKING for operations: PROBE READ ERASE
WRITE
-------------------------------------------------------------------------------------
The IDs of this flash chip are:
Manufacturer ID: 1f
Memory Type: 8401
So I checked the datasheet and added support in flashchips.h at line 154:
#define ATMEL_AT25SF041 0x8401 /* Adesto */
and in flashchips.c at line 2178:
{
.vendor = "Atmel",
.name = "AT25SF041",
.bustype = BUS_SPI,
.manufacture_id = ATMEL_ID,
.model_id = ATMEL_AT25SF041,
.total_size = 512,
.page_size = 256,
.feature_bits = FEATURE_WRSR_WREN,
.tested = TEST_OK_PREW,
.probe = probe_spi_rdid,
.probe_timing = TIMING_ZERO,
.block_erasers =
{
{
.eraseblocks = { {4 * 1024, 128} },
.block_erase = spi_block_erase_20,
}, {
.eraseblocks = { {32 * 1024, 16} },
.block_erase = spi_block_erase_52,
}, {
.eraseblocks = { {64 * 1024, 8} },
.block_erase = spi_block_erase_d8,
}, {
.eraseblocks = { {512 * 1024, 1} },
.block_erase = spi_block_erase_60,
}, {
.eraseblocks = { {512 * 1024, 1} },
.block_erase = spi_block_erase_c7,
}
},
.printlock = spi_prettyprint_status_register_at25df,
.unlock = spi_disable_blockprotect_at2x_global_unprotect,
.write = spi_chip_write_256,
.read = spi_chip_read,
.voltage = {2700, 3600}, /* 2.3-3.6V & 2.7-3.6V models
available */
},
Compiled, Works perfect!
So you can add support for this beast in your next version.
Bye,
Jens
