Hi,
We have made a PCB with STM32L073RZT6 and programming it with NUCLEO-L073RZ and it works well.
Now we are testing with STM32L152RET6 and STM32F411RET6.
STM32L152RET6 is getting programmed and works well with NUCLEO-L073RZ but not STM32F411RET6.
Is it that STM32L073RZT6 and STM32L152RET6 both belong to " L series " so its working with NUCLEO-L073RZ and not STM32L152RET6.
Please confirm if we can program STM32F411RET6 with NUCLEO-L073R development board or have to get NUCLEO-F411RE

They all share the same STM32F103 parts on the ST-LINK side. Make sure the firmware on the ST-LINK is current. Check what SWO and NRST pins are doing on the internal target, disconnect solder-bridges if appropriate, along with the SWDIO/SWCLK jumpers.

I have updated the firmware on the ST-Link but still not programming.
Also, reconfirmed the SWO bridge is not connected and NRST pins bridge is soldered so the on nucleo reset button can be used.
Still I am able to program other STM32L073RZT6 and STM32L152RET6 but not STM32F411RET6.
Other difference I found that STM32L073RZT6 and STM32L152RET6 both have speed 32Mhz while STM32F411RET6 has speed 100Mhz.
But this should not have any issue with the Blinking code (coded from Mbed online while NUCLEO-F411RE platform was selected.

Leaning here to there being a problem with your F411 circuit. Done any other validation on this platform showing the IC is functional? Can you bring up the ROM based System Loader and talk to that via the USART1 ?
Checked voltage levels on VCAP and NRST pins?
