Aircon compressor and fans, industrial control, washing- machine. I still assume, the errors are linked to the njtrst function of the PBA pin of the STM32F7.

I removed the GPIO initialization of PIN PB4 - which is connected to NJTRST. Also, the jlink errors do not appear in a working copy with minimal changes. For some unknown reason, the "Active read protected" message does not come reliably.

How to get Technical Assistance from a Technical Support Moderator.

When I flash, I get this message:Įrror starting target flash write algorithmĮrror writing to flash at address 0x08000000 at offset 0x00000000Ĭan someone please provide some guidance? I guessing those are clues, but I don't know for sure. I keep seeing messages saying "Device Security Bit Set" and "stm32x device protected".

However, as you can see in the image, unlocking of STM32 devices is supported natively (upper marking in the screenshot) If you type in 'con' multiple times, does it unlock the device multiple times We also provide a tool to reset the option bytes of STM32 devices to factory default. XPSR: 0x01000000 pc: 0xfffffffe msp: 0xfffffffc the unlock command only supports the devices listed. Target halted due to debug-request, current mode: Thread Next, I telnet to the server and run the following commands:Ĭleared protection for sectors 0 through 67 on flash bank 0 Openocd -f interface/stlink-v2.cfg -f target/stm32f4x_stlink.cfg I can't seem to get the right combination of commands to unlock the device. I've been trying all day to flash my stm32f4discovery using the OpenOCD cmd line on windows.
