Troubleshooting SPI Transmission Errors for Image Data on ESP32

still on Object Detection with MicroPython and OV2640 Camera Module Using ESP-WROOM-32, how can i transmit the image over SPI i keep getting a persitent error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "spi.py", line 42, in write
OSError: SPI transmission error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "spi.py", line 42, in write
OSError: SPI transmission error

i have checked and ensure SPI pins are correctly connected and configured and verified the SPI baudrate and other settings are appropriate for the image size

Solution:

Emm...try to lower the baudrate and sending the image data in smaller chunks maybe that would work
