CREATOR does not upload firmware to dash button
I use Arduino IDE with Ubuntu 16.04.
Everything used to work. I uploaded a firmware a few times. But once it just started returning:
Build options changed, rebuilding all Sketch uses 301454 bytes (14%) of program storage space. Maximum is 2097152 bytes. /home/alexeyisme/.arduino15/packages/RAK/tools/ameba_tools/1.0.9/upload_dap_linux /home/alexeyisme/.arduino15/packages/RAK/tools/ameba_tools/1.0.9/ram_all.bin uploading... cp "/home/alexeyisme/.arduino15/packages/RAK/tools/ameba_tools/1.0.9/ram_all.bin" /media/alexeyisme/MBED/;sync upload finish
It says upload finish, but dash button firmware is not updated. I think I just don't see what I do wrong.
Hi, can you use the windows 7 system to try it?
interesting, I have the same problem. I'm on macOS, don't have any windows pc
At the beginning, the upload took a while and I could the LED flashing quick on the Dash (RAK611) while uploading. Now, nothing happens anymore.
Maybe I stwitched from JTAG to DAP mode? How can I switch back?
just found this output in console:
Start RESET program target_set_state : RESET Program failed jtag_init() failed main : usb disconnected
That's the problem. but how do I fix the reset program?
solved it! I had the OTA example on the dash which apparently called
sys_jtag_off(). To fix it, I uploaded a new image via OTA, not using
pinMode. Once this was flashed I could upload another image directly over Creator PRO again.
Sorry another update: no, NOT solved Problem is back again: this time
I don't have any OTA connected, so no chance to avoid
sys_jtag_off()to be called. what to do? which pin is
A2and checks the Battery status? from reading code, this one has to be > 800. Help!
if the A2 pin is dangling(without plug battery), the voltage level will be less than 800mv, so the sys_jtag_off() will not be called, and the download process will be normal.
if not plug battery and still download fail, try click below key to see...
thanks for your quick reply. I tried this, but is doesn't help. I'm now trying just to connect the Creator Pro Board to my mac, and even this is not (always) working. I assume the board is broken. the reset DAP chip button works only if I press the button very very hard a couple of time - then the board resets/reboots. Will talk to @rakwireless for advice...
Can you take a photo about your wire connections?
Sure (see below) - I double checked it, it's exactly as displayed on your picture.
Meanwhile I added an Arduino for the serial communication & reset connection - now the flashing works again in ~80% of the cases. I still assume the Creator PRO Board has something broken... Anyway, I can say the flashing problem is SOLVED (for now).
