Hello,
I need to refresh board specific values(board's S-out value) on web page every time get-still button clicked.
So I'd change code app_httpd.c and index_ov5640.html but it has no changes.
What am i missing?




static esp_err_t capture_handler(httpd_req_t *req)
{
camera_fb_t *fb = NULL;

Hello,
In my example, while loop in main.c seems working in 1.437ms period
and I need some calculation in us.

int64_t oldTime, currentTime;
int16_t deltaTime;

while(1) {
oldTime = currentTime;
currentTime = esp_timer_get_time();
deltaTime = currentTime - oldTime;
printf("deltaTime: %d\n ...

Case closed,

Was not exactly the PSRAM issue.
Please refer https://www.esp32.com/viewtopic.php?f=13&t=18950 if may someone interested.

Regards,

Well... problem solved.
In my case, problem caused because below one pin between
ESP32 and OV5640 was mistakenly disconnected.

CONFIG_CAMERA_PIN_HREF=16

Thanks for advice anyway!

System keep rebooting while frame buffer init and here's log while.
I have no idea why free space on PSRAM shows abnomal values after allocating 960kBytes.


I (2556) camera: Detected OV5640 camera
E (2556) camera: in_bpp: 2, fb_bpp: 2, fb_size: 983040, mode: 3, width: 2560 height: 1920

I made logs

static esp_err_t camera_fb_init(size_t count)
{
if(!count) {
return ESP_ERR_INVALID_ARG;
}

camera_fb_deinit();

ESP_LOGI(TAG, "Allocating %u frame buffers (%d KB total)", count, (s_state->fb_size * count) / 1024);
ESP_LOGI(TAG, "Get Total size %d KB in PSRAM", heap_caps_get ...

That is strange... can you decode that backtrace? Is the firmware 100% the same on both boards, or did you need to change things because e.g. different board layouts?


I think Flash memory size and OV5640 camera interface is different.
Below is about my custom board.

Hello, problem solved.

- I guess problem somewhat caused by limitation of my USB-to-UART dongle,
which connect my custom board and PC.
After I change download tool as "flash_download_tool_v3.8.5" and lower
UART baudrate as 115,200, it started work.
- ESP32-WROVER_E in my custom board turns out ...
