Hi all.
Let me tell you the problem I'm facing and I googled for finding some help but without luck.
The problem I have in hands is as next. I was using Nucleo WB55 to use the STM32F103CBT6 to program a microcontroller I have in a custom PCB for an end product I'm designing. Until yesterday everything was working OK. Since yesterday the STM32CubeIDE is telling me that is not possible to connect with the programmer. I checked what's the message shown by this last program and it says:
Target no device found
Error in initializing ST-LINK device.
Reason: No device found on target.
After seeing this, I downloaded the ST-Link Utility to connect to the board and the program says:
Now, having this message I proceeded to use the STM32CubeProgrammer to see what it can tell me and it shows:
14:45:15 : UR connection mode is defined with the HWrst reset mode
14:45:15 : ST-LINK SN : 066EFF313335415043141328
14:45:15 : ST-LINK FW : V2J43M28
14:45:15 : Board : P-NUCLEO-WB55
14:45:15 : Voltage : 0.00V
14:45:15 : Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication
After a firmware upgrade of the board, the message shown changed and is as below:
15:25:16 : UR connection mode is defined with the HWrst reset mode
15:25:16 : ST-LINK SN : 066EFF313335415043141328
15:25:16 : ST-LINK FW : V2J43M28
15:25:16 : Board : P-NUCLEO-WB55
15:25:16 : Voltage : 2.67V
15:25:16 : Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication
Is needed to mention also that the COM led is in red color and LED5 has been also turned ON. LED4 was turned ON and now is OFF.
The question is: what can I do to recover the board to be able to keep going on my programming of my end device?
Thank you in advance,
Braian
