The Nucleo Board takes clock (8MHz) from ST- Link Programmer and we want to switch it to external (8MHz) crystal which is not working.We programmed the RCC->CR register to 0X03030300U so that it sets to external crystal but it shows 0X03050305U ( HSE...

We were able to solve the issue using Keil IDE, but our complete code is in mbed OS and there the issue still persists.If anyhow this issue is solved in mbed OS its done.

We need the same 8Mhz Clock as the STlink programmer gives to the main microcontroller (STM32L073RZ).Need to use only HSE only.

Thank you for all your support.All the connections including the resistors, caps of 20pF and 8MHz crystal are properly connected at its place.Have done after reviewing the BOM and schematics from ST.If any other info most welcome.Thank you.

No we are not using HSEBYP, We are setting 0X03030300 which set the HSEON and clears HSEBYP.Only issue is that the HSERDY bit is not set.
