LimeUtil --update interrupted

Cypress FX3 USB microcontroller has an integrated boot loader, which starts automatically after power-up or reset and when no valid firmware is present in the FLASH memory.

For USB microcontroller firmware upgrade, please use the “CyControl.exe” application from package.

If FLASH memory is empty or connector J17 (on LimeSDR-USB board) is open, USB3 microcontroller boots-up into bootloader mode. Cypress drivers from package must be installed first. Download the package here. Run the “USB Control Center” application and select Cypress USB BootLoader line as shown in Figure 5.
