Introduction

This release of CSL for TMS320TCI6486 contains peripheral programming (functional and register level) APIs for TCI6486 modules. The list of modules supported in this release is listed in CSL User Guide. This set of APIs provides peripheral abstraction that can be used by higher layers of software.

This release includes:

·  Compiled library of supported CSL modules.

·  Interrupt Controller (INTC) module.

·  Archived sources and build scripts. (Separate zip file)

·  API Reference Guide.

EMAC Main Device Instance Structure contains core specific information which is updated run-time.

Such run-time update requires cache writeback/invalidation during packet flow in multi-core scenarios when cache is enabled.

In this release, EMAC Core Instance Structure is extracted from the original EMAC Main Device Instance Structure to avoid run-time cache operations.

SDOCM00072518

CSL_DEV_PRI_ALLOC_EMAC*RX register definitions are invalid.

In this release, CSL_DEV_PRI_ALLOC_EMAC* register definitions are provided. To keep backward compatibility, the original CSL_DEV_PRI_ALLOC_EMAC*RX and CSL_DEV_PRI_ALLOC_EMAC*TX fields are mapped to the newly defined CSL_DEV_PRI_ALLOC_EMAC* fields.

SDOCM00073259

MDIO shows link status changes for only one PHY.

MDIO originally uses only one set of USERACCESS registers and it always finds the first alive PHY and monitors it.

In order to monitor two PHYs simultaneously, this release utilizes both USERACCESS register sets and enables application to specify a PHY address for monitoring.

SDOCM00073260

There is long delay for MDIO to show the link status up when a EMAC port is opened the first time

With the option of specifying a PHY address for monitoring by MDIO (fix for SDOCM00073259), it is observed that the delay is reduced.

SDOCM00074287

I2C and Cache API addition.

In this release, CACHE_disableCaching() function is added for Cache, and CSL_I2C_CLEAR_ALL Macro is added for I2C.

SDOCM00075118

SRIO does not provide configurability for LOG_TGT_ID_DIS in PER_SET_CNTL.

In this release, logicalLayerDisable is added in CSL_SrioControlSetup structure to support the LOG_TGT_ID_DIS configuration.

What’s New

This is a maintenance release for TMS320TCI6486. The major updates to this release include:

·        Use Code Generation Tools 7.0.3 in example projects.

·        EMAC Core Instance Structure is extracted from the original EMAC Main Device Instance Structure to avoid run-time cache writeback/invalidation during packet flow.

·        MDIO supports simultaneous monitoring of two PHYs. User can specify a PHY to be monitored by MDIO.

·        Cache API addition: CACHE_disableCaching() function is added.

·        I2C API addition: CSL_I2C_CLEAR_ALL Macro is added.

·        CCSv3 “.pjt” files are deprecated.
