目前老外收集的一点资料:
https://github.com/keirf/Greaseweazle/wiki/STM32-Fakes
1.Cannot program at 921600 baud. Success at 115200 baud.
2.Cannot start firmware from System Bootloader (Bootloader may not set the Reset SP?)
3.Debug registers return valid non-zero info (contravenes Erratum 2.3 of genuine parts)
4.Writing to backup registers, and then turning off the backup interface clock, seems to lock up parts of the chip: Future writes to certain registers hang forever with no exception or reset
5.I2C peripheral won't allow CR1_ACK to be set in the same write that sets CR1_PE
6.DMA peripheral generates spurious extra completion interrupts and is generally prone to lockup |
