When running the code https://github.com/jomjol/AI-on-the-edge-device/ on esp32 cam
Esp32 cam module
The idea is to run a sketch which requres psram so I Picked up this board
with the specifications
Features :
ESP32-CAM :
- The smallest 802.11b/g/n Wi-Fi BT SoC module.
- Low power 32-bit CPU, can also serve the application processor.
- Up to 160MHz clock speed, summary computing power up to 600 DMIPS.
- Built-in 520 KB SRAM, external 4MPSRAM.
- Supports UART/SPI/I2C/PWM/ADC/DAC.
- Support OV2640 and OV7670 cameras, built-in flash lamp.
- Support image WiFI upload.
- Supports TF card.
- Supports multiple sleep modes.
- Embedded Lwip and FreeRTOS.
- Supports STA/AP/STA+AP operation mode.
- Support Smart Config/AirKiss technology.
- Support for serial port local and remote firmware upgrades (FOTA)
this is the error that I get when I run the sketch
same error on web page
Steps to replicate the error
Esp32 cam connected to esp32 => connected to laptop using the usb cable
Connection
uoT of esp32 cam => Tx0 of esp32
u0R of esp32 cam => RX0 of esp32
power to esp32 cam via usb 2nd usb port of laptop
5v and gnd
also tried programming by giving esp32 cam 5v via vin of esp32 (worked both ways while writing sketch)
esp32 is bypassed by connecting En to ground
also while writing gpio and gnd shorted in esp32 cam and removed while running the ode later on
esp32 micro usb port is used to connect it to laptop usb port
-----
writing the sketch
my python directory is c:\python27
and my esptools.py is in C:\Python27\esptool-master\esptool-master
So I have copied the contents of the firmware folder to this folder (as I was not sure of esptool was picking up the path correctly)
from the command prompt in this folder I ran
esptool.py erase_flash
Next on the command prompt I entered the command
esptool.py write_flash 0x01000 bootloader.bin 0x08000 partitions.bin 0x10000 firmware.bin
This time I did not have to press the reset button a 2nd time and the code went on to execute
Once back on the command prompt I removed the gpio0 and gnd jumper and reset the device.
For me it is connected on 192.168.1.18
Loading the page I find
As you can see the images do not load.
On further investigation of the log I see the error
Not enought PSRAM available. Expected 4.194.304 MByte - available: 2162758 Either not initialzed or too small (2MByte only) or not present at all. Firmware cannot start!!
The same error can be seen from the arduino ide serial monitor
While searching for a fix I found a video https://www.youtube.com/watch?v=iUgxwbfkIqU
In the comments I see a number of people having this error.
And as a possible fix I see
This basically says to modify the sdkconfig file and make
CONFIG_SPIRAM_IGNORE_NOTFOUND=y
Now with some difficulty I could locate my sdkconfig but my file did not have a "CONFIG_SPIRAM_IGNORE_NOTFOUND" entry
So I further researched and found this link
and added CONFIG_SPIRAM_IGNORE_NOTFOUND=y
Now since I was using python command so I was not sure if this setting would be referred so I closed my arduino ide and restarted it.
Opened the esp32 camera webserver sketch and loaded to my esp32 cam
this works ok as before however when I try to write https://github.com/jomjol/AI-on-the-edge-device/
it gets written as shown above however the same error persists.
"Not enought PSRAM available. Expected 4.194.304 MByte - available: 2162758
