Posted on April 12, 2018 at 10:08I have designed a board with STM32F334R8T6. The STM32 pins are configured as in the attached file (I do not think there is a problem here since I have already used the same configuration without problems). The microcontroller is programmed with a STM32 NUCLEO BOARD using the 6-pins connector (3.3V, PA14, GND, PA13, NRST, PB3): also in this case I do not think there is a problem since I can program without problems other boards using the same NUCLEO board and connector.
When I try to connect to the STM32F334 microcontroller using STM32 ST-LINK utility I get the following message:
09:33:

09:33:

: Failed to read memory @08010000!
The programmer seems not to be able to access the microcontroller flash memory. However I can not figure out the reason for this.
If I try to program the microcontroller the following messages are displayed
10:01:45 : [Prova_F334.bin] opened successfully.
10:01:47 : Memory-Loader error
10:01:47 : Error occured during erase operation!
The option bytes are set according to the attached file.
Can anyone help to solve this problem?
Thanks.
