Program a new L152 chip (in STM32CubeIDE)

[NiJo]

Hello

I did some basic testing to set up, write code and program the STM32 F103 (bluepill) with the STM32CubeIDE and everything worked fine!

In a project I would like to design my own PCB and use the L152C8T6 chip. So I purchased some new chips from Digikey, solder the chip to a breakout board and connect it to STMicroelectronics ST-Link v2 (as I did with the F103)

But with the L152 chip it seems like I can't program the Flash memory at all. But in some way I can use the system memory.

When in debugging mode this message appear and the LED is not blinking when I run the code on L152 with Boot0 connected to ground.

With Boot0 high and Boot1 to ground the LED is blinking when I run the code but another message appear. And the LED do not blink when the chip is powered up again.

With F103 everything works fine.

As the pin out is the same for F103 and L152 I also tried to solder the L152 chip to the bluepill board, but with the same result.

I also know that the L152 chip is new out of the box and most likely "clean" of code that might not be the case in F103 Bluepill.

Is it something that I missed or do I need to do something extra / different to program the new L152 chip?

Sorry for a long message, but I am lacking ideas how to progress :(

Gagh, you can close (and remove :) ) this question, I had a L152CBT6 chip, not a L152C8T6. So when you chose right chip in the CubeMX it was no problem ;)
