Function Documentation

void LCM_scrubMemAuto (  LCM_Control *  ctl  )

Architecture specific implementation of LLCMSCRUBRUN command. LCM_scrubMemAuto() implements the LLCMSCRUBRUN command for rad750.

unsigned int LCM_scrubSurom (  LCM_SuromError *  rom, unsigned int *  hcs, unsigned int *  bcs )

Scrub through SUROM contents to check integrity. Parameters: rom  (out) SUROM memory error counts by segment hcs  (out) Header checksum failure by segment (1 => failed) bcs  (out) Body checksum failure by segment (1 => failed) Return values: LCM_SUCCESS  Always LCM_scrubSurom() performs memory reads through the rad750 SUROM to check for integrity.

unsigned int LCM_scrubTaskInitialize (  LCM_Control *  ctl  )

One-time call in LCM task context to start the scrub sub-function. Parameters: ctl  (in) LCM control block LCM_scrubInitialize() builds up the CPU common facilities to run the memory scrubber and handle memory/PCI exceptions.

static unsigned int suromRead (  LCM_Control *  ctl, unsigned char *  dst, const unsigned char *  src, unsigned int  cnt )  [static]

Read SUROM memory. Parameters: ctl  (in) LCM control block src  (in) Source address dst  (in) Destination address cnt  (in) Number of bytes to read Return values: x  Number of bytes read (not necessarily the number requested!)

Variable Documentation

static const unsigned char * LCM_suromSegment[LCM_L_SUROM_SEGMENT] [static]

Initial value: { LCM_K_SUROM_BASE, LCM_K_SUROM_0_BASE, LCM_K_SUROM_1_BASE, LCM_K_SUROM_2_BASE, LCM_K_SUROM_3_BASE } How to get at the offsets/sizes for the memory mapped segments in RAM.
