hi everyone, I have a mini2440 device and recently COM1 of my device doesn't work anymore. I don't know what happened but I think some board connection is damaged. when I use hyper terminal in NOR flash mode I can't get any data, but The others (2 COMs)are working greatly yet!,I would be glad if someone can help me out to fix the damage and yet if i can't how I can change default COM1 for NOR mode to another COM port(to change windows or linux)? Thank you all
Hi You will not be able to change the bootloader in NOR memory as that bootloader is not opensource. In your device, maybe the MAX3232 is damaged. If you are comfortable in working with hardware then you can take the RXD0 and TXD0 connection from CON1 of your device, keep another MAX3232 outside and make the connections yourself. You will also need 3.3V DC and the GND connection for your new MAX3232. And then connect your serial cable to this new MAX3232 instead of the COM1 of your device. Best of luck.
