Useful information for RT1050

i.MX RT1050 is the first set of processors in NXP's crossover processor family, combining the high-performance and high level of integration on an applications processors with the ease of use and real-time functionality of a microcontroller. As the first device in a new family, we have had some learning and improvements that have come along the way. There have been some changes and improvements to the processor and also our enablement for the device. This can result in some revisions of hardware and software not being directly compatible with each other out of the box. In particular, some software that has been released for the A0 silicon revision (found on EVK boards) doesn't run on the A1 silicon revision (EVKB boards).

In order to minimize the risk of compatibility issues, we recommend that all customers move to SDK 2.3.1 or higher. The SDK 2.3.1 is listed as supporting the EVKB hardware specifically, but the SDK is compatible with the EVK (non-B) hardware.

We also recommend that customers using the DAPLink firmware for the OpenSDA debugging circuit built into the EVK/EVKB update to the latest version available on the site.

The flashloader package has also been updated. Rev 1.1 or later should be used (Flashloader i.MX-RT1050).

There are many application notes available for RT1050. Many of these application notes were written based on the original silicon revision and early releases of enablement software. We are in the process of reviewing the published application notes and application note software to prioritize updating them where needed based on the latest enablement and recommendations.

If you are in a situation where you need to use SDK 2.3.0 on A1 silicon, the most likely problem area involves some new clock gate bits that were added on the A1 silicon revision. These bits weren't present on the A0 silicon, so SDK 2.3.0 will clear them which disables external memory interfaces. If you comment out 

the call to BOARD_BootClockGate() that is in the BOARD_BootClockRUN function (found in the clock_config.c file), that should allow the SDK 2.3.0 software to run on an A1 silicon/EVKB.
