Local RAM (RAM) and Static RAM (SRAM) Tests

MVME167BUG/D3 3-7

Code Execution/Copy - CODE

Copy test code to memory and execute. The code in the memory under test

copies itself to the next higher memory address and execute the new copy.

This process is repeated until there is not enough memory, as specified by the

configuration parameters, to perform another code copy and execution.

Command Input:

167-Diag>RAM CODE

or:

167-Diag>SRAM CODE

Response/Messages:

Note that in all responses shown below, the response "RAM " is RAM or SRAM,

depending upon which test set is being performed. After the command has

been issued, the following line is printed:

RAM CODE: Code Execution/Copy............... Running --->

If all parts of the test are completed correctly, then the test passes.

RAM CODE: Code Execution/Copy............... Running ---> PASSED

The test failure mode is typified by the nondisplay of the PASSED message

above after more than about 1 minute, which indicates that the MPU has

irrecoverably crashed. Hardware reset is required to recover from this error.
