Updating WIFI shield

Postby Raoof_M » Sat Apr 11, 2020 7:36 pm

Hi,

I tried updating the WIFI shield firmware using the fw_update script but an error showed up (OSError: Could not find the file).

I copied the winc_19_6_1.bin file to a uSD card, then resetted the the camera but would always get the same result.

Thanks

Hi, please make sure the file is written, try safe remove/eject the drive before resetting the cam.

You need to copy the file again, safe eject and then reset. There's another way to update using the debugging header on the wifi shield a power supply and Arduino (google WINC1500 firmware update) it's much more harder to update the firmware this way.
