[flashrom] Support for Dediprog SF100 / Multiple dediprogs

[Mike Hibbett]

Hi Stefan,

I'm using gcc 4.8.2, the distribution compiler on my Ubuntu 14.04 64 bit box.

Make CONFIG_DEDIPROG=yes gives:

cc -MMD -Os -Wall -Wshadow -Werror   -D'CONFIG_DEFAULT_PROGRAMMER=PROGRAMMER_INVALID' -D'CONFIG_INTERNAL=1' -D'CONFIG_INTERNAL_DMI=1' -D'CONFIG_SERPROG=1' -D'CONFIG_RAYER_SPI=1' -D'CONFIG_PONY_SPI=1' -D'CONFIG_BITBANG_SPI=1' -D'CONFIG_NIC3COM=1' -D'CONFIG_GFXNVIDIA=1' -D'CONFIG_SATASII=1' -D'CONFIG_FT2232_SPI=1' -D'CONFIG_USBBLASTER_SPI=1' -D'HAVE_FT232H=1' -D'CONFIG_DUMMY=1' -D'CONFIG_DRKAISER=1' -D'CONFIG_NICREALTEK=1' -D'CONFIG_NICINTEL=1' -D'CONFIG_NICINTEL_SPI=1' -D'CONFIG_OGP_SPI=1' -D'CONFIG_BUSPIRATE_SPI=1' -D'CONFIG_DEDIPROG=1' -D'CONFIG_SATAMV=1' -D'CONFIG_LINUX_SPI=1' -D'NEED_PCI=1' -D'NEED_USB=1' -D'HAVE_UTSNAME=1' -D'FLASHROM_VERSION="0.9.7-r1791"' -o dediprog.o -c dediprog.c
dediprog.c:761:2: error: initialization from incompatible pointer type [-Werror]
  .write_aai = dediprog_spi_write_aai,
  ^
dediprog.c:761:2: error: (near initialization for ‘spi_programmer_dediprog.write_aai’) [-Werror]
cc1: all warnings being treated as errors

fixed with this quick hack:

diff dediprog.c dedipro.c~

< static int dediprog_spi_write_aai(struct flashctx *flash, const uint8_t *buf, unsigned int start, unsigned int len)
---
> static int dediprog_spi_write_aai(struct flashctx *flash, uint8_t *buf, unsigned int start, unsigned int len)


< 	return dediprog_spi_write(flash, (uint8_t *)buf, start, len, DEDI_SPI_CMD_AAIWRITE);
---
> 	return dediprog_spi_write(flash, buf, start, len, DEDI_SPI_CMD_AAIWRITE);

Regards,

Mike.

Hello Mike,

reading the manpage would help with the multi-device problem: The dediprog module supports that with a device parameter (in a rather awkward but yet sufficient way).

What was your build issue?
