I ran into a problem when uploading using CMD ( WCHISP worked fine). I got CH552G chip with 2.4.0 bootloader version I checked the VNproCh55x tool repository but I can't find any clue thanks

I don't know what cause this but resoldering the chip fixed the problem, one thing to notice is this CH552 is plugged in to a nested MAO8608 USB hub chip (MAO8608 1x4---->MAO8608 1x4 at port A----->CH552 USB at port C)

After some successful upload, the error show up again, I use a CH551 to replace the CH552 on the board and it uploaded just fine
