[raydem8]

Hello,

First, thanks for the software.

I am trying to read the S25FL256S with arduino uno modified to 3.3V. And for a moment the arduino reads flash but always stop with the message Command not accepted!0. I tried to put the SPI speed to 1 Mhz but the problem is the same. Cna you help me please?

Depending on the UART chip (ft232, ch340) used in the Arduino, you need to select the speed of the COM port.
#define UART_SPEED 1000000 in the sketch
arduino_baudrate="1000000" in sittings.xml
