Hi everyone, I have a problem with our proprietary bootloader on STM32L151, STM32L451 and STM32F303 micros.I transfer the content of a flash page via any interrupt-controlled interface (CAN, UART, USB etc.). If all the data for a flash page is availa...

Hallo everybody,I'm still very inexperienced with the board and the tools.I start Unico and contact the STEVAL-MKI109V3 and get the following error:Please can someone give me a hint on how I can update the STEVAL-MKI109V3 board and where I can get th...

Hello BenedictHeyl, hello alister,thank you for your suggestions. When we were still using a serial bootloader (i.e. receiving data from a flash page, then deleting and writing the flash page and then requesting next data via handshake) we did not ha...

Hi Mike,We also tried mass erase as a workaround. You can do that, but our solution is faster.Your idea about corrupt flash content is good. The very first OB_Launch action may lead to incorrect address access and a hard fault error. That would be ha...

Hi Mike, Thank you for your prompt reply. We have been working with all types of ST microcontrollers for 10 years now. We would like to locate and understand the problem."The problem really only occurs when we want to flash a brand new microcontrolle...

These are older ST functions, but they have always worked correctly so far. The only difference seems to be that we now want to use an A-type microcontroller. The software is partially migrated from an STM32L151C8T6.

Hello, I am a colleague of ralf239955_stm1.The problem really only occurs when we want to flash a brand new microcontroller.We make do with a workaround by flashing twice. It is noticeable that after the first flash the Read Protection is set to Leve...

Problem with our proprietary bootloader. Interface interrupts may come too quickly while flash pages are being deleted and written.

Re: Can't set Option Byte with the attached function for the Micro STM32L151CBT6A Only when the controller is new from factory. If we erase and reset the option bytes the STM32 afterwards new flashing it works.
