Thanks. I committed this along with 4ce2d37 on top. Separately, this sets USBSEL=2 which is in contrast to the reference manual https://www.st.com/resource/en/reference_manual/rm0444-stm32g0x1-advanced-armbased-32bit-mcus-stmicroelectronics.pdf which states USBSEL=1 should be used to enable PLLQCLK. In the past I tried enabling the PLLQ for USB and could never get it to work - I guess this is why. Do you have any further information on this discrepancy? -Kevin |

STM32G0B0have notHSI48but onlyPLLQ, So we set the USB clock source toPLLQ. In this way, bothSTM32G0B0andSTM32G0B1can use the samefirmware.binfileSigned-off-by: Alan.Ma from BigTreeTech [email protected]
