Hi cckeo, I have tried to use i2c-tool for detect, get, set register on hi253 camera but it not work. I use this patch for add hi253 Camera on kernel configure: https://gitorious.org/angstrom/angstrom-linux/commit/046dac666301c0df22679424169675045c70defd Why i can't detect Camera sensor although i have supported Power sequence, MCLK (24MHz) for it ?
