I have committed a slightly revised version in r1894 after realising that there are two mistakes in the proposed change. dediprog_firmwareversion was defined already, it was simply initialized in the hunk below to some (in)sane default. However, this should not happen at all in this patch but a later one. > > @@ -45,6 +45,17 @@ static int dediprog_endpoint; > > #define DEDI_SPI_CMD_PAGEWRITE 0x1 > > #define DEDI_SPI_CMD_AAIWRITE 0x4 > > > > +enum dediprog_leds { > > + LED_INVALID = -1, > > + LED_NONE = 0, > > + LED_PASS = 1 << 0, > > + LED_BUSY = 1 << 1, > > + LED_ERROR = 1 << 2, > > + LED_ALL = 7, > > +}; > > + > > +static int dediprog_firmwareversion = FIRMWARE_VERSION(0, 0, 0); > > + > > #if 0 > > /* Might be useful for other pieces of code as well. */ > > static void print_hex(void *buf, size_t len) The else path below was simply wrong. > > @@ -406,10 +399,10 @@ static int dediprog_spi_write(struct flashctx *flash, const uint8_t *buf, > > /* Round down. */ > > bulklen = (len - residue) / chunksize * chunksize; > > ret = dediprog_spi_bulk_write(flash, buf + residue, chunksize, start + residue, bulklen, dedi_spi_cmd); > > - if (ret) { > > - dediprog_set_leds(PASS_OFF|BUSY_OFF|ERROR_ON); > > - return ret; > > - } > > + if (ret) > > + dediprog_set_leds(LED_ERROR); > > + else > > + dediprog_set_leds(LED_PASS); > > > > len -= residue + bulklen; > > if (len) { This ensures the firmware version is reset at shutdown, but this has nothing to do with the LEDs handling... > > @@ -781,6 +774,8 @@ static int dediprog_shutdown(void *data) > > return 1; > > #endif > > > > + dediprog_firmwareversion = FIRMWARE_VERSION(0, 0, 0); > > + > > /* URB 28.
