FMUv2 / Pixhawk Silicon Errata
- STM32F427VIT6 (errata)
Flash Bank 2 and full speed USB device exclusive
Silicon revisions up to rev 1 (revision 3 is the first not affected) can produce errors / data corruption when accessing the 2nd flash bank while there is activity on PA12, which is one of the USB data lines. There is no workaround / software fix for this, except to not use the flash bank #2. Since USB is needed to program the device, Pixhawk revisions built with silicon revisions < rev 3 can only use up to 1MB of the 2MB flash of the microprocessor.
