Other Parts Discussed in Thread: ALP, USB2ANY
Greetings,
We have 3 kits, when we tried to power up the third one exactly like the image provided by @Vishy ( to power it up from J24), it worked and the PC recognized the derserializer in ALP software.
However the other 2 kits still couldn't be recognized, we tried to re-flash the firmware of the microcontroller using USB2ANY Firmware Loader.exe, we flashed USB2ANY_2_7_0_0.txt but with no luck.
we now suspect that the old way we were powering the kits with, it might have caused over voltage or something. (see the attached photos), we were powering the kit by applying 12V on J26 & 9V on J32.
When we power up anyone of the 2 (non-working) kits through J24, 5 leds on the board go on (exactly like the working one). see the second image.
Could we know what may be causing this problem in these 2 kits, do you have any test points we could investigate in those cases ? ( we also had a quick check on the deserializer rails yesterday, but all voltage seem okay)
