Hi,
I saw arduino severino a while back and thought it'd be cool to try and recreate a similar thing for some small projects.
I got the schematic and altered it, as I didn't want to program using DB9 (I don't have a good DB9/RS232 to USB converter). And i had used another USB-TTL converter (CP2102 from Silicon Labs) earlier, and so I thought I could use it instead of the general FTDI.
So, i made a board and got a cheap PCB made for it. And something really weird happened :
I burnt the bootloader, and was able to program the arduino with Blink and other codes.
While testing, I tested Serial Comm, and it did not work. i.e. I was getting gibberish on SerialMonitor. The same character keeps appearing ... so, if I tell it to print("a"), it doesnt, but always prints "p" (with 2 dots on top ... ) So, basically, it seems like some bits got corrupt.
(Baudrates and all were fine.)
I have no clue why this happened.
... I could program it, so Serial should work fine, but it doesn't.
Anyone faced such an issue ? Please help me out here, it's driving me crazy ...
