oleeeeee! that's the correct address of the gc0609 CSI camera!
the trick is that MCO (master clock out) is an ALT (alternative) function, once i'd set that correctly, it was up.
gpio_set_mode(GPIOA, GPIO_MODE_OUTPUT_50_MHZ, GPIO_CNF_OUTPUT_ALTFN_PUSHPULL, GPIO8); rcc_set_mco(RCC_CFGR_MCO_HSECLK);
a quick "soft reset" call and i managed to read the chip version: 0xa. woo!
