Starting target validation of NN model I get: "LOAD ERROR: STM32 - read timeout 10032.0ms/10000ms"

[ACane.1]

How can I solve it? Which timeout is it? Is it a timeout of STM32CubeAI or something set on the board?

I'm using the STM32F746NG Discovery board, and I'm validating the network making use also of the external SDRAM.

I'm sure the procedure is correct because with a lighter model everything works fine.

See the screenshot attached.

Thanks
