4 Software Changes Between AM263 and AM263P SDK

Component AM263 AM263P
ADC IP Type 3
Driver v1		 New hardware feature now supports IP Type 4.
SDK includes drivers (v2), documentation, SysConfig, and examples in SDK for the new additions with Type 4.
Type 4 additions include the following:
  • DMA trigger (added feature)
  • SOC Trigger (added feature)
  • Trigger Repeater block (new feature set)
  • PPB Aggregator (new feature set)
  • External Channel Selection
  • Open Short Detection (new feature)
ADC Safety,
ADC Safety Aggr		 N/A New hardware feature.
SDK includes driver, documentation, and SysConfig to support the following features:
  • Comparison against any 2 selected results across most ADC modules with the exception of the 3MSPS or ADC-R modules.
  • Usage of interrupts when one or more threshold reaches occur across all the ADC Safety Tiles
Resolver N/A New hardware feature.
SDK includes driver, documentation, and SysConfig to support the following features:
  • Sequencer modes to support single motor single core, single motor lockstep core, and dual motor dual core configurations.
  • Demonstration of a safety diagnostics feature.

Software implementation of Track2 loop is included with the provided examples.
Sigma Delta Filter Module (SDFM) IP Type 2.1
Driver v0		 No hardware changes.
Additional SDK examples provided:
  • Workaround for SDFM Digital Filter interrupt reassertion issue
  • SDFM-ECAP loopback example
SoC driver - ControlSS CTRL N/A New hardware feature.
SDK includes driver, documentation, and SysConfig to support the following features:
  • Dynamic clock gating
  • How to configure the EPWM to use WLINK
Trip and Sync XBAR N/A New hardware feature.
SDK includes driver, documentation, and SysConfig to support the following features:
  • New XBARs - EXTCHSEL, EQEP SOCAB XBAR, new groups to XBARs
  • XBAR clock gating
Opti-Flash
  • FLC
  • RL2
  • RAT
 N/A New hardware feature.
SDK includes driver, documentation, and SysConfig to support the following features:
  • RL2 example for how to configure the new feature
  • FLC example for early CAN response
OSPI QPSI New hardware feature.
SDK includes driver, documentation, and SysConfig to support the following features:
  • Flash Diagnostics Example
  • Flash DMA Example
  • Flash IO Example
  • Use of two chip select pins

QSPI is also supported with FLASH API which internally uses OSPI, however this requires software updates when transitioning from AM263 to AM263P.
SBL OSPI SBL QSPI SBL-OSPI is provided for AM263P
eXecute In Place (XIP) support N/A New hardware feature.
Enabling XIP functionality does not require dedicated drivers.
With XIP functionality offered in AM263P, it is possible to change the boot flow on a per application basis to leverage XIP.
Firmware Over the Air Update (FOTA) N/A New hardware feature.SDK includes driver and documentation.
On The Fly Encryption and Authentication (OTFA) N/A New hardware feature.
SDK includes driver and documentation.
Smart Placement N/A New compiler support.
This has been developed because Sitara Microcontrollers have different levels of memory with varying latency between the core and peripherals.
Smart placement distributes functions and other linker-placed objects across different memories by assigning critically based on the frequency of use to minimize perform degradation.
This new feature is available for other Sitara Microcontroller SoCs in addition to AM263P once released.
Function-call Based Layout N/A New compiler support.
This feature is part of Smart Placement and is geared towards improving the performance of key usage for boot acceleration. However, this can be applied to any start-up code.
This feature operates by grouping start-up code functions and data in execution order into address regions that can be programmed using a Fast Local Copy (FLC) hardware accelerator.
This new feature becomes available for other Sitara Microcontroller SOCs in addition to AM263P, once released.
