![]() ![]() Is there anything else I've missed? I will read through the document that you recommended, but if you have any suggestions, that would be great. And I am not able to upload any code.Īnd then I tried to add a 4.7uF capacitor between VCAP (Pin 30) and GND, as soon as added it, the FAIL.TXT Jumps out again, original problem has come up again. Hi Clive One, I have tried what you said today, by adding power to VDDA/VERF+, The FAIL.TXT has gone, however, when I upload code from Keil (I am using STM32Cube MX combined with Keil to program the MCU), it returned with Core is held in reset. Note: this post was migrated and contained many threaded conversations, some content may be missing. I am not sure how to fixed this, if anyone can help, that would be appreciated. The interface firmware FAILED to reset/halt the target MCU. MBED.HTM), there is one additional file calledįAIL.TXT, and when I opened it out, it shows: This time, when I connect the program to my computer, same storage disk (NODE_F411RE (D:)) has jumped out, however, in stead of usual two files ( ![]() Left Pin from JP1 (next to USB Power)-VDD (Pin 19) Everything works fine.Īnd then I connected the same programmer to my STM32F411RE Chips with the same pins as following: With the connection above, I can program my Nucleo board with external ST-Link programmer that I cut off before. Left Pin from JP1 (next to USB Power)-VDD (CN7-5) When I connect the programmer to STM32F411RE Nucleo 64 Board: The pins are connected the same as how I connect my programmer to the nucleo board. I tried to use the same ST_Link Programmer to program the chips by connect the 8 pins from the programmer to the chips, but it does not work. I have been use it to program other STM series Board with no problem.Ĭurrently I am doing a project that is using STM32F411RE Nucleo 64 Board and I have a custom made PCB with STM32F411RE chips on it. Hi, I have a ST_Link Programmer that was cut off from STM32F411RE Nucleo 64 Board (zero ohms resistors SB12, 13, 14, and 15 have been also removed).
