3.1.1 CCS Linker File Features for IPE

NOTE

These linker file features are current as of CCSv6.1.1. Earlier versions of the CCS linker file do not have all of these features, so it is recommended to use CCSv6.1.1 or later when using this method for enabling IPE.

The CCS linker .cmd files for devices with IPE support include some sections for placing IPE code and data. All that user code has to do is to tell the compiler what variables and functions should be placed within these predefined sections. The following snippet is from the MSP430FR5969 linker cmd file:

GROUP(IPENCAPSULATED_MEMORY) { .ipestruct : {} /* IPE Data structure */ .ipe : {} /* IPE */ .ipe_const : {} /* IPE Protected constants */ .ipe:_isr : {} /* IPE ISRs */ .ipe_vars : type = NOINIT{} /* IPE variables */ } PALIGN(0x0400), RUN_START(fram_ipe_start) RUN_END(fram_ipe_end) RUN_END(fram_rx_start)
  • .ipestruct – This segment is for containing the IPE initialization structure that includes information about the address location of the IP Encapsulated memory boundaries and control settings. There is more information about the IPE initialization structure in the MSP430FR58xx, MSP430FR59xx, MSP430FR68xx, and MSP430FR69xx Family User's Guide. The user should not place any data in this section—when using the built-in CCS IPE tool, the tool generates the required values and places them here.
  • .ipe – This segment is for any code functions the user wants to place in the IP Encapsulated area.
  • .ipe_const – This segment is for any constant data that needs to be encapsulated. This could be things like encryption keys, or calibration info, encapsulated code version numbers, or any constants used by the encapsulated code that should be kept hidden. Application dependent.
  • .ipe: _isr – This segment is for any Interrupt Service Routines (ISRs) that are needed as part of the IP encapsulated user code.
  • .ipe_vars – This segment is for any data variables that need to be encapsulated. Any variables used solely within the IP encapsulated code should be also placed in the IP encapsulated area instead of in RAM for the most security – otherwise observation of changes to RAM could be used to try to reverse-engineer the functionality of the encapsulated code. This is of course application dependent.

Further at the bottom of the linker file, observe there is a section for calculating the IPE initialization values for the IPE structure:

/****************************************************************************/ /* MPU/IPE Specific memory segment definitions */ /****************************************************************************/ #ifdef _IPE_ENABLE #define IPE_MPUIPLOCK 0x0080 #define IPE_MPUIPENA 0x0040 #define IPE_MPUIPPUC 0x0020 // Evaluate settings for the control setting of IP Encapsulation #if defined(_IPE_ASSERTPUC1) #if defined(_IPE_LOCK ) && (_IPE_ASSERTPUC1 == 0x08)) fram_ipe_enable_value = (IPE_MPUIPENA | IPE_MPUIPPUC |IPE_MPUIPLOCK); #elif defined(_IPE_LOCK ) fram_ipe_enable_value = (IPE_MPUIPENA | IPE_MPUIPLOCK); #elif (_IPE_ASSERTPUC1 == 0x08) fram_ipe_enable_value = (IPE_MPUIPENA | IPE_MPUIPPUC); #else fram_ipe_enable_value = (IPE_MPUIPENA); #endif #else #if defined(_IPE_LOCK ) fram_ipe_enable_value = (IPE_MPUIPENA | IPE_MPUIPLOCK); #else fram_ipe_enable_value = (IPE_MPUIPENA); #endif #endif // Segment definitions #ifdef _IPE_MANUAL // For custom sizes selected in the GUI fram_ipe_border1 = (_IPE_SEGB1>>4); fram_ipe_border2 = (_IPE_SEGB2>>4); #else // Automated sizes generated by the Linker fram_ipe_border2 = fram_ipe_end >> 4; fram_ipe_border1 = fram_ipe_start >> 4; #endif fram_ipe_settings_struct_address = Ipe_settingsStruct >> 4; fram_ipe_checksum = ~((fram_ipe_enable_value & fram_ipe_border2 & fram_ipe_border1) | (fram_ipe_enable_value & ~fram_ipe_border2 & ~fram_ipe_border1) | (~fram_ipe_enable_value & fram_ipe_border2 & ~fram_ipe_border1) | (~fram_ipe_enable_value & ~fram_ipe_border2 & fram_ipe_border1)); #endif

The user does not have to modify anything with these settings, but this demonstrates how the linker file is working with the CCS IPE tool settings, to determine the values to go in the IPE initialization structure.
