Hi
I'm testing DLPDLCR230NPEVM after connecting it with the Raspberry PI 4 via 40 pin connector.
When I run the flash_write_fpga.py and other script, I get an error message saying
Traceback (most recent call last):
File "flash_write_fpga.py", line 150, in <module>
if __name__ == "__main__" : main()
File "flash_write_fpga.py", line 87, in main
i2c.initialize()
File "/home/pi/src/projector/i2c.py", line 59, in initialize
_i2c.open()

self.fd = os.open('/dev/i2c-%d' % self.busnum, os.O_RDWR)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/i2c-7'
It seems that the relevant i2c device is not available.
what I only have in /dev are as follows:

What might be the cause of the problem?
Thank you
