So i have changed the programming engine for the 25VF064C from "spi_chip_write_1" to "spi_chip_write_256". I have tested the 25VF064C with the new engine and it works fine. For the 25VF032B i have changed the programming engine from "spi_chip_write_1" to "spi_aai_write". I have tested this engine, too, and found it working (speedup was from 228 to 113 seconds). While testing i found that some commands needed by some of the algorithms are not in the OPCODE table. So i have implemented the on-the-fly reprogramming of the OPCODE table (in the ICH engine). _______________________________________________ flashrom mailing list [email protected] http://www.flashrom.org/mailman/listinfo/flashrom
