Detailed Description

Function definitions for secondary boot RTOS phase.

Author:

D.L. Wood

Implements the first stage of the LAT secondary boot process. Loads the secondary boot executable from the SIB board lower EEPROM bank, SIB board upper EEPROM bank, or from the secondary boot module RAM temporary buffer, and executes the entry function SBC_Init().

---

Define Documentation

#define BOOT_DIAGS_ADDR (   )     (&debugDiag)

Get access to the boot diagnostics memory structure. For RAD750 targets, this is the real thing. Otherwise, it points to the local debug structure.

#define SBC_DEV_NAME   "/mem/sbc"

The name to use for the loader memory device.

#define SBC_ENTRY_NAME   "SBC_init"

The symbol name of the SBC executable entry function.

Function Documentation

void VXW_AppInit (  void   )

Start LAT application initialization by executing secondary boot code module. The goal is to get and load the secondary boot executable (SBC module 0). The secondary boot flags indicate the location to get the source image. The file header and file checksum are verified, and the file data is inflated if necessary. The module is loaded using loadModule(), and the SBC entry point is called. The symbol SBC_init() should be defined in the SBC module.

static void VXW_AppInitError (  unsigned int  status, unsigned int  index, unsigned int  data, BOOT_Diagnostics *  diag )  [static]

Reports errors from the SBC initialization process. The relevant information is stored in the boot diagnostics structure. For flight configurations, the error is considered fatal, and the system is rebooted. Otherwise, the error information is simply printed. Parameters: status  An SBC MSG code indicating the error condition. index  An SBC MSG code indicating the progress index at time of error. data  Error specific data to help diagnosis. diag  A pointer to the boot diagnostics area.

static int VXW_AppInitRead (  unsigned int  addr, void *  buf, unsigned int  size, const BOOT_Diagnostics *  diag )  [static]

Read in data from the SBC executable module file. Parameters: addr  The address or offset to read from. buf  The buffer to hold the read data. size  The number of bytes to read. diag  A pointer to the boot diagnostics area. Return values: 0  Success. -1  Failure.

debugDiag [static]

Initial value: { 0, (BOOT_DIAGS_SBF_RTOS_SOURCE_EE0 | BOOT_DIAGS_SBF_MOD0_SOURCE_EE0 | BOOT_DIAGS_SBF_MOD1_SOURCE_EE0), 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, {0, 0}, 0, {0, 0, 0, 0, 0, 0, 0, 0} } A fake boot diagnostics structure for non-RAD750 targets.

sysStartType
