Got a new Revelprog, installed latest firmware+software.
I have some odd speed issue. At first it was constantly dumping at low speed (ca 300kbit/s) no matter what setting I used. Then it switched for whatever reason and now is constantly at 8-9MB/s.
The self test was OK. I could dump smaller SPI chips with either speed. But I got problems with larger ones. Not sure if this is only a speed issue, since it is ISP it could also be other reasons. But changing clock speed sometimes helped in these cases.
I also tried to reinstall drivers. It is a Windows 11 machine and the libusb-win32 driver failed. Not sure if this is an issue, since Zadig should be used for installation which worked fine.
Any ideas?
