HAL_PWR_EnterSTANDBYMode() will still wait properly, but HAL_PWREx_EnterSHUTDOWNMode() will immediately return to RUN mode.What do you think is the cause of immediate wakeup?As shown below, the only code difference is whether to enable HAL_PWREx_Ent...

I am sending with CDC_Transmit_FS by USB CDC, but USB_TransmitCplt_Callback is not called unless the other computer receives it on the COM port.How do I time out or abort a send?MCU: STM32L433CCUxLibrary Version: STM Cube FW_L4 V1.17.0

I solved it myself.The cause was that nRST_SHDW was unchecked in the option byte.Best regards,

Thank you for your reply. It's completely convenient for me.As you say, I think it's equivalent if you choose between UART and SWD.I'm investigating whether it can be UART + SWD or UART only.I use UART in the product, but I am investigating whether i...

Thank you.The reason GETID fails may be because Bootloader mode is terminated.I'm still testing on the evaluation board, so I can connect with ST-LINK.I haven't tried attaching yet, so I'll try it.Best regards,

As you said, I think it's a Go command.The log of the relevant part is as follows, and Ack (0x79) is returned for Go command, so the command seems to be successful.My application works with Power On Reset, but it doesn't work with Go command, I thoug...
