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
