STM32F411 Errata

Is there a new version of the Errata document? The one the website (Doc ID 027036) is revision 1 and was released on 20-Oct-2014.

Why do I ask? The STM32F412 - has an Errata about DMA2 corruption when managing AHB and APB2 peripherals and I'm wondering if the STM32F411 has the same issue. IIRC, the STM32F410 has the same errata.

For what it is worth, the STM32F412 errata, Doc ID 027846, is on revision 6!

Thanks.

Hi HarjitS,

The STM32F411 errata sheet will be updated to add the DMA2 limitation (applicable only on GPIO for STM32F411).

You can refer to

http://www.st.com/content/ccc/resource/technical/document/application_note/27/46/7c/ea/2d/91/40/a9/DM00046011.pdf/files/DM00046011.pdf/jcr:content/translations/en.DM00046011.pdf

to get more details on how to apply the suggested workaround (Section: Inverting transfers over DMA2 AHB ports consideration).
