Cannot flash wi-fi jpeg streamer example about aideck-gap8-examples

[Gualor]

Update: I managed to solve the issue by swapping a few cable connections between Olimex ARM JTAG TINY H and the 20 to 10 pin adapter, I just supposed the 20-10 connector was mirrored (as other products are). So this part of the issue was not due to a bug on the AIdeck side.

However, after the JTAG programming was successful the example I was testing wifi_jpeg_streamer gave the following error:

test.c:4:10: fatal error: tools/frame_streamer.h: No such file or directory
 #include "tools/frame_streamer.h"
          ^~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Have you build the SDK with 'make gap_tools' and 'make pulp_os' ? Btw, you should use SDK version 3.5 for the wifi streamer example since we are still experiencing a bug with 3.6 and up.

Hi,
thank you for the reply, I followed the full installation of the tutorial (which I assume also installed pulp_os and gap_tools) using the command make sdk. Thank you for the suggestion, I will try out gap_sdk v3.5 as soon as I can.

Another question, I saw in the example that NINA uses freeRTOS while GAP8 uses PULP OS, is there any particular reason for this choice? Would it be possibile to use freeRTOS on both MCU?

Best,
Lorenzo

Could you elaborate the solution a bit more? We did not see this problem so maybe something has changed with their 20-10 connector?

[Gualor]

Yes I will elaborate my previous answer. As it was the first time using this JTAG programmer I wasn't familiar with the pinout, I have both an Olimex arm usb tiny h and Olimex arm jtag 20-10 pin connector, both of them have female pin headers.

The beginner mistake I made was assuming the pinout of the two devices were mirrored so by using jumper cables I just connected 1:1 the pins (in the same position but flipped), but in reality the pinout is exactly the same (not the reflection) and so the jumper connections made are now not as tidy (had to swap and twist a row of pins), but now it works perfectly.

Couldn't find any images of the two devices connected together, I hope my explanation was sufficiently clear.

Best,
Lorenzo

Thanks for the clarification. We use a 1.27mm flat cable like in this picture but we have also experienced that the Olimex flat cable can be a bit "glitch".
