Hi!
I bought a bot board and a basic atom 28 pin chip. When i turn the power on the speaker makes a noise once on reset of the chip and then a few seconds later start making a repeatedly clipping sound but when i connect them on my pc the atom program doesn’t find an atom chip. Where is the problem? I use a usb to serial cable. I could really use your help.
thank you

Hello Christos,
the sound is generated by a factory default program to test the chip and will be gone after you flash your first program. as for the USB/Serial device, make sure that you are using the correct (virtual) com-port (you can find out via the device manager).
Have Luck!
I have double checked my port and i still cant get my pc to find the atom chip 
I have lowered the FIFOs down to 0, too. Maybe is the serial to usb cable or my pc. I don’t know 
Hello!
I am not quite sure: i am connection via USB to Serial as well. But i think i once read a thred here with another guy having the same problems. go and try a search in the forum.
regards
I have read the previous post but nothing of those advises helped me How did he manage to solve his problem?
I managed to get my atom chip into programming mode. When i press debug it starts to compile and then to write. After a while a message pops up saying “Error connecting with Atom”. Any suggestions what might be the problem?
Not all USB to Serial adapters are created equal. Some switch there signals fast enough(eg. When getting into programming mode the RTS line must switch at the correct time and then switch off within the correct time). Many USB adapters don’t do this correctly which causes problems getting into programming mode.
Also, just because you can program your chip consistently doesn’t mean the debug mode will work. Debugging(using the default settings) is pretty data intensive on the serial port. If you are having trouble getting into debug mode you can try lowering the debug baud rate(see the System Setup dialog if using the Atom or Preferences if using the AtomPro). You should also NOT use serial commands on the S_IN and S_OUT pins when trying to debug. They will conflict with the debug data stream causing irratic behavior.
It’s not clear if the problem you are having is happening while programming the chip or if the communications problem is happening while trying to enter debug mode(after programming finishes).

I have tried both usb to serial canle and usb to serial adapter. I get the same message “Error connecting to atom” while the program is being written on my atom. I have tried to lower the FIFO down to 0, i have tried change the debug baud rate…I don’t know what else to try. It could be atom’s fault?
If you are able to program the Atom then it’s unlikely its the Atoms fault you are having problems debugging. If the Atom can be programmed then all the I/Os used for communication while debugging are working. I suspect your usb to serial adapters are not able to keep up with the constant back and forth communications. I ussually recommend the BAFO BF-810 usb to serial adapter if a customer is having problems like yours. It’s a $17 USB to Serial adapter that I use myself so I know it works.
