Connect/Download to target

Legacy Legacy AirPrime modules
1

Hi,

i’ve got a problem with downloading an application to target.

I have the development Kit with Q2686.

RS232 is correctly (straight cable) connected with UART1
UART1 is enable, LED “EN1” is on
Flash LED is on
BOOT is off

I can open the Com-Port on PC correctly, but the Target Monitoring Tool can not find a target (with Auto dedect), not the DWLWin either.
Of course i can not recive any information about the Target…

Any idea?
The development kit is second hand, are there perhaps any fuse bit witch can be cleared?

Thanks 4 help

Hi, did your Q2686 is soldered to the Devboard? If not try to solder the pins or make a good contact with the Devboard pastil (introduce a soldered wire between Q26 pins and the Devboard pastil)

:smiley:

Yes, the Q2686 is well soldered :slight_smile: It was exactely in use like it is installed now

4

may be your Q26 is bugged and need to be reflashed… use DWLWIN, dont forget the 10K resistor between Gnd and boot pins

5

since you’re using the Q2686 dev-board. forget the above statement about the resistor, but use the boot-switch.
as you can read in the development kit guidlines.

Exact, that works also without the 10k resistor…
So did you try to reflash your device?

7

Hellow!

Now it works! Thank you!
So the only problem left is how to develeop with OpenAT :slight_smile:

Is there any startguide? Step by Step?

Before you start, are you familiar with ‘C’ programming in general?
And embedded ‘C’ programming in particular?

Oh yes,
i’m an embedded c-programmer (regular occupation). Actually, my problem is to know, when i have to use which command and what kind of Handler exists and so on.

I try to understand the samples and so i come forward slowly

10

by the way, all the adl documentation also exists in the headerfiles.
(made it easier for me to find a lot of the information)

11

yes, i know.

my big problem actually is, that the target connection isn’t continuous and the Trace don’t work

12

are you using a usb->serial converter or a rs232 connection on the pc?

13

I’m connected directly with rs232

14

Ok, my Firmware seems to be realy buggy.

I can not connect to the Target anymore. No with Target Monitoring Tool, nor with DWLWin.

Last time, the problem was a too long rs232-cable, but now, i have no idea left…
How can i reflash the Q26 when DWLWin (after several “Starting up the target”-Try’s) tell me: “Boot failure: cannot connect with the target. Cannot boot up the remote target: giving up”. Wireless CPU AutoDedection don’t work eighter.

The Boot-Pin is low of curse

Hi, I have the same problem, did you find a solution?

Please help :open_mouth:
