[quote author="ian"] You procedure is: 1. setup UART 2. hit b and choose a PC-side baud rate 3. close terminal/reconfigure terminal for the new PC-side speed 4. connect again and hit space, but nothing happen [/quote]
1. Check 2. Check 3. Check 4. Freeze See output (not much to see)
HiZ>b Set serial port speed: (bps) 1. 300 2. 1200 3. 2400 4. 4800 5. 9600 6. 19200 7. 38400 8. 57600 9. 115200 10. BRG raw value
(9)>8 Adjust your terminal Space to continue
I tried to press space before and after setting the speed. Basically as soon as I change the speed there is no response anymore, no echoing of key-presses too If I reset (poweroff/poweron) the buspirate, I get key-press echo again for both wrong and right speed settings. I tried other speeds as well with the same result
thanks for the reply. Yep, indeed I read Taykens post. The difference between the Arduino and the AVR is simply the bootloader. Its looking for a bitstream via the serial connection right after an reset. This is, it does not need an AVR programmer but only a simple serial connection.
I thing I can manage to get it running. In the "worst" case I switch over to the ICSP connector and use the buspirate as a AVR programmer as you mentioned in your post. However, I'm still curious why I can't access my serial terminal anymore after I changed the speed of the buspirate.
This has nothing do to with AVR, its simply my terminal is frozen after I change the speed.
just was trying to use the buspirate in transparent UART mode to program an Arduino which comes without USB interface (no USB serial bridge). I followed Ians description in a similar post. As far as I understood, I have to enter UART mode, and make sure the buspirate is using the same speed on the PC side, the actual software (Arduino IDE or AVRdude) are using (using the "b" command). The buspirate tells me... Please adjust your terminal settings Press space to continue.
However, whatever I tried I was not able to reconnect. I can open the serial port, but there is no communication with the buspirate. No garbage, nothing, simply plain dead. There is even no echo of any key-press.
I used screen and minicom with no luck. PB v3a is on the last firmeware-version 5.10 (IIRC) Host is Arch Linux
Thanks for helping

CC. I basically, do not see the reason why I have to change the speed twice. First I set it up for UART mode and then for the PC side. I can see some use for the terminal mode. However, as soon as someone starts the transparent macro, I would say there is no need for different speeds. Can't we simply set the PC-site datarate to whatever was selected in the UART mode within the macro? Guess this might be something many people trap into.
