I saw in some forums that for this kind of board we can use the reboot loader command to reboot directly into maskroom mode. Unfortunately, the current kernel configuration was freezing during reboot commands.

After debugging extensively using UART logs, I discovered the problem was the restart ...

In our provided firmware images, GPIO4_C0 is configured as the BOOT key. Since it is not pulled up by default, it may randomly enter flashing mode under certain conditions.
You can modify the U-Boot configuration to release GPIO4_C0 for other purposes. However, after doing so, entering flashing ...

There are many possible hardware-related causes. After ruling out power supply issues and RESET pull-up problems, the issue may still be related to the USB routing—for example, not implementing a 90Ω differential impedance, mismatched trace lengths, and so on.

If there are no confidentiality ...

Hello,

I'm developing an carrier board for the core1106, can I use these two GPIO4_C0(pin 26) and GPIO4_C1(pin 27) as normal analog input (1.8v) ?
I’ve seen in other discussions that one of these pins must always be pulled up. Could you please clarify why this is required?

D+ and D- correspond to Data+ and Data- of USB 2.0.


I was able to boot the Core1106 without any issues, with all the required pull-ups (RESET, BOOT, and USB_DET_IN). However, I can’t get the USB to work.
I connected USB D+ and D− to pins 23 and 22 respectively, the VCC into pin 80, and GND to ...

Hi. would You please finally put simple but complete schematic of correct connecting /run Core1106G3 module? with pin numbers, pullup resistors and voltage supplies? and any description ?

because i tried to follow Your info about pins, but module still not started. should it draw 5v from usb? or ...
