F29H85X-SDK is the Core SDK providing collection of all foundational software components required to accelerate application development . It includes device-specific drivers, bit-fields, libraries (math, DSP, Control, Calibration, Communication, Flash API and Security client), peripheral examples, utilities, hardware files, and documentation. Application specific software and hardware files are delivered through additional Software Development Kits (SDK). For more information, visit F29-SDK

Fixed Issues

Fixed Issues

Sl. No	Issue ID	Issue Description
1	C29SDK-690	SSU Tool: Default LINK1 configuration blocks Flash plugin in SSUMODE2
2	C29SDK-609	Flash error builds due to specific settings
3	C29SDK-536	I2C Pin Qualification Pin Type to be changed to Open Drain

Known Issues And Limitations

There are few limitations and known issues associated with this release

Limitations

Sl. No	Description	Workaround
1	Memory Allocation (specifically for Flash memory regions) through the Sysconfig tool is only supported for the 4MB Flash variant of the device. This includes the Memory Allocator tool as well as the SSU Configuration tool.	None
2	Limited F29P58X and F29P32X device support Only one example is provided which demonstrates F29H85X device emulation as F29P58X or F29P32X	The device emulation may be extended to other examples as required The below driverlib function to be called in the example 'main' function to emulate as F29P58X and F29P32X respectively: SysCtl_emulateDevice(SYSCTL_EMULATE_F29P589DU5); SysCtl_emulateDevice(SYSCTL_EMULATE_F29P329SM2);
3	In SSUMODE2 and SSUMODE3, 'memcpy' function cannot be called from link other than LINK2	Define 'memcpy' function local to the link
4	FreeRTOS: Support for task-specific FPU register saves has been removed	FPU registers are now always saved for all tasks. Any usage of vPortTaskUsesFPU() can be omitted.
5	Only Windows build is supported for the the Transfer examples	None

Known Issues

Sl. No	Issue ID	Issue Description	Workaround
1	C29SDK-857	CPU timer period inaccuracy	Configure the CPU timer period by making the Timer prescaler equal to 0. For eg, to generate timer period of 200 us use the following configurations for 200 MHz: Prescaler = 0 Period in cycles = 40000

Compatibility Information

Sl. No	Module	Description
1	Bootflow	The entry point address for RAM configuration for examples is changed from 0x20100010 to 0x20100000
2	Bootflow	The '_c_int00_noargs' call is changed to '_c_int00'
3	Multicore Examples	Addition of Certificate generation for CPU3 in FLASH configuration 'CPU3_RESET_VECTOR' modified from 0x10400000 to 0x10401000
4	EPG Examples	GPIO34 is changed to GPIO2
5	Driverlib	All inline functions are attched with 'always_inline' attribute
6	ERAD driver	Below APIs are updated to pass pointer to structure as argument: ERAD_profile ERAD_enableInterruptOnAddressHit ERAD_countAddressHits
