To send a file from PC to S4:
1. Press 'SETUP' on the S4 and change file to 'BINARY' and check the other settings whilst you are there. I use 115200,8N1, no handshaking
2. Setup serial port on Linux PC to correct parameters with setserial
3. On the S4, select chip type and then press 'RCVE'. Make sure you set the range correctly (for a 4Mbit chip it's 0000 - 7FFFF) and press 'ENTER'
4. The S4 is now ready to receive, I use the following command to transfer the file:
Code: Select all
dd if=/filename.rom of=/dev/ttys0
To receive, press SEND instead of RCVE and then use this command:
Code: Select all
dd if=/dev/ttys0 of=/filename.rom
