RG500Q Booting issue

Hi,

We have one of the boards that has an RG500Q module. Recently, we’ve been encountering the following issue:

  • It does not boot and is not recognized in the device manager.
  • However, when we switch to emergency flash mode, it shows the port, and we are able to flash it. After switching back to normal mode, the same problem arises as it is not detected in the device manager.
  • when we connect to the Debug Port to check the boot logs using Tera Term software,

The logs appear as follows:

Dear @Pavan
Could you share your current firmware? And which series did you use?RG500Q-EU or others?

Dear @Pavan
Could you try to execute "fastboot reboot "?

Dear @silvia

Thank you for your response.
When we tried on a Windows OS, it showed “ADB Devices not found.” However, after we switched to a Linux OS, we were able to execute “fastboot reboot,” and now the module is working fine.
