Hi.. Lately we just got this zoom board and try to capture an image from it (We're doing camera sensor business), however, it just doesn't work.
Here is the detailed info.
1) TWL4030 problem
After I insert battery connector to socket, the board begin to boot. Then I got a log(see attachment) which indicated omap3430 can't get response from twl4030.
2) ov3640 driver question
a. GPIO setting
Is this definition correct? In Schematics, CAMERA_POWER_DOWN seems should be GPIO_7, I also try that , but it still can't work.
#define CAMERA_RESET_GPIO 98 // for SDP ES2.0
#define CAMERA_POWER_DWN 58
b.I2c no accknowledge from ov3640
static int
ov3640_detect(struct i2c_client *client) {
u8 pidh, pidl;
//...
if (ov3640_read_reg(client, OV3640_PIDH, &pidh)) <--- this will cause 'No
accknowledge' response
return -ENODEV;
if (ov3640_read_reg(client, OV3640_PIDL, &pidl))
return -ENODEV;
//...
return 0;
}
So our conclusion is that the sensor is not powered correctly.
Can you help us with this... or we need to ship it back to fix TWL4030.
Thanks a lot..........
