I don't know that device at all, but there are various programmer modules in flashrom that can give you hints how to add support for it. "/dev/hidraw" sounds as if it is Linux-specific therefore I suggest you take a look at linux_spi.c and mstarddc_spi.c. To get an idea of how to hook up the programmer and what else is necessary for a complete patch you can take a look at the patch that added the mstar ddc driver: http://code.coreboot.org/p/flashrom/source/commit/1860/ or the preliminary (and probably broken) programmer driver creation script: http://patchwork.coreboot.org/patch/3836/ -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner _______________________________________________ flashrom mailing list [email protected] http://www.flashrom.org/mailman/listinfo/flashrom
