Memory Dump with STM32CubeIDE shows also 0x0 at this addess. The Errata shows no entry to this problem.uint32_t* ptr = 0x1FF80078;VREFINT_CAL_VAL = *ptr;Is it a typo in the dataheet?

That's it!!I have the 151xc-type, so the VREFINT_CAL_ADR ist 0x1FF0800F8/9I spent hours in searching all documents/net, even the application notes don't mention the define VREFINT_CAL_ADR_CMSIS . Poorly documented!The next problem: i have two devices...

I use a STM32L151 in a battery application, i have to measure VCC. To do this exactly i try to read the Vrefint-calibration Value, stored at 0x1ff80078/9 (STM32L151 Datasheet pg. 56) But if i try to access to this address via a pointer, i read 0x0.
