Hi,

Which USB-TTL converter do you use? What is the output of PuTTY and mincom? Post it here. Try using -m c123 instead of -m c123xor

HI again,

I replaced my ttl converter, now my phone is able to communicate via serial port but osmocon is unable to write hello world binary. The output of following command is given

$ ./osmocon -p /dev/ttyUSB0 -m c123xor ../../target/firmware/board/ compal_e88/hello_world.compalram.bin

output:

If you cannot get @ftmtoolerror with minicom then your jack is NOT working or your TTL converter is broken (was burnt during soldering?:)

If you have another OS (e.g. Windows machine) you can put the device in the PC, find out which serial line it is using, run PuTTY, set Destination to Serial, COM9 (or what you find out), speed 115200, connect. Then push the power button on motorola, you must see @ftmtoolerror there. If not, try another jack, another TTL converter, remove phone plastic case as I told already..

No more ideas :)

Oh okay. The headphone jack is working fine, i have tested it. And helloworld isn't working. Can you tell some other method to test phones connectivity with my system.

Hi,

Check the picture https://osmocom.org/attachments/download/2091/motorola_c123_ hello_world.jpg

I mean the outer plastic case of the phone may not allow your jack to be inserted at the whole length to thoe whole even if it looks like OK. It depends on your jack case shape.

Hi,

Thanks for replying back.

I am not using virtualized environment. No success with minicom test. What exactly do you mean by jack is being plugged on the whole length, i didn't get it.

Hi,

Are you sure the jack is being plugged on the whole length? Did you get success with minicom test? I would recommend you to disassemble phone and check whether the jack plugged an the whole length. Do you use virtualized OS or normal? If virtualized, try to play with the settings.

KR, Anton
