If you don't mind, check my work -- the shmFwCtrl.c code seems to do the equivalent of: // initiate eeprom transfer wl12xx_reg_write32(wl, ACX_REG_EE_START, ACX_REG_EEPROM_START_BIT); // *** msleep(40); msleep(40); // sets spad4 to 0, I guess this is some kind of address register? wl12xx_reg_write32(wl, ACX_EEPROMLESS_IND_REG, 0); // everything from here on out is the same - read spad2 and 3 then boot. *** NB: I redefined ACX_REG_EEPROM_START_BIT to BIT(0) -- BIT(1) looked wrong unless that define is meant for something else. The state machine is kind of hard to read, but it seems like there should be more to it. Did I miss anything as far as you can tell? I get all zeros from spad2 and spad3 so it's not working with just the above... > Please let me know if you have any questions.
