Hello,
My name is Hye-Woon Jang, and I am currently using the RD33772C14VEVM board.
After purchasing the board, I connected it to a DC power supply as shown in the attached photo. Since I do not currently have a suitable 12 V battery available, I am supplying 12 V using the power supply instead.
The connections are as follows:
- 12 V + : VBAT+, K30_12V_L
- 12 V - : VBAT-, GND_KL31_DOWN
I am contacting you because, even when only the power supply is connected, the red RESET LED turns on and continues blinking at intervals of approximately 0.5 to 1 second, as shown in the attached photo.
Should I understand this behavior as the board being repeatedly reset?
I am asking because the LED brightness appears to be different from when I manually press the RESET button.
I would like to run a model using TRACE32. However, when the board is connected to TRACE32, the RESET indication in TRACE32 blinks at the same time as the RESET LED on the board, and it seems that TRACE32 is therefore unable to establish a connection with the target.
I would appreciate it if you could confirm whether this RESET LED behavior is normal and advise me on how to resolve the issue. Thank you for your assistance.
Best regards,
Hye-Woon Jang
