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; esp_err_t r...

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", deltaTime)...

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 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_total_size(MAL...

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. ESP32_DOWNLOAD_TOOL.jpg # # Auto...

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 that ...
