hello, please, I flash my quad dso and the program is blocked, now dso quad blocks, no more display, I can not find how to put in DFU mode, there exist a program for reset the bios and application, please help me
If you have really corrupted the DFU bootloader then the only way to recover is to use the STM serial bootloader to reflash that. That means taking the device apart and attaching a serial connection to the internal serial connector and using a new DFU image file. There are a few threads on this forum about how to do that.
BUT you should exhaust all the other possibilities first. E.g trying other USB hosts and also describing how you got in this state as that might help assess whether the DFU is really corrupt.
Thank you for the information I have to command(order) a converter On eBay but on the connector cn7 what does(throws) to use? I have been operated for the hand thus I waits some day to flash dso, and with it I collect the information, thank you for your help(assistant)
