|
- [x] How to integrate sara chip. Get LTE-M sim-cards.
|
|
|
|
- [ ] Testing Protocol: Define exactly what tests are being done and why and write everything down.
|
|
|
|
- [ ] How can I use JTAG?
|
|
|
|
- [ ] Buy Heat camera
|
|
|
|
**Todo Working Verification:**
|
|
|
|
1. - [x] Visual Inspection. Are all parts at the right place?
|
|
2. - [x] Power Inspection. Hook up 5V supply and test all power rails.
|
|
3. - [ ] LED inspections. Are the LED's working as expected?
|
|
No. Orange led is to weak. Blue led is always on, without network connection.
|
|
4. - [x] See if coral works. Can I ssh into it?
|
|
5. - [x] Test connectors. USB-A, USB-C
|
|
6. - [ ] Test connection through UART-pins to flight controller
|
|
7. - [x] Test fan: Does it work properly?
|
|
8. - [ ] Test SARA-Chip. Does it boot? Can I communicate with coral? Read instructions carefully.
|
|
9. - [ ] Test arducam with google coral: Is a custom driver needed?
|
|
It has not worked so far.
|
|
10. - [ ] Test Usb-cams with coral: does this work?
|
|
Yes it worked without any problems.
|
|
11. - [ ] Test both UART connections: do they send what you want?
|
|
|
|
12. - [ ] Is I2C working properly?
|
|
13. - [ ] Use JTAG to verify proper functionality:
|
|
14. - [ ] Is WIFI and Bluetooth working properly, or is it interfering with something?
|
|
|
|
**Todo Performance Testing:**
|
|
|
|
1. Compare different antennas: All for the same SARA and then do bandwidth test in different conditions: Indoors, Outdoors, underneath trees, between skyscrapers, around glass, etc.
|
|
2. Compare usb plugs on both sides: Is there a bandwith difference? Use iPerf for testing
|
|
3. Test connection between corals through usb-c: does it work? What bandwitdth? Compare to 2 devboards.
|
|
4. Measure current draw of the whole board
|
|
5. Is airflow from drone enough? Measure temperature.
|
|
6. Heat camera: look at thermal performance of pcb. Are there areas where it can be improved
|
|
|
|
Possible fixes for problems:
|
|
|
|
Quickly make intermediate board: double sided with coral connectors. Like that you can access the pins that are hidden.
