2 fcrChipTest fcrChipTest Tests the functionality of FC Router FPGA. Synopsis fcrchiptest [--slot slotnumber] [-unit number] [-testtype type] Description Use this command to test the FC Router Field-programmable gate array (FPGA). This test verifies that all SRAM and register data bits in each ASIC can be independently written and read successfully. The method used is to write a walking 1 pattern to each location. This is accomplished by writing a pattern of 0x00000001 to register N, performing a DMA read, and ensuring that the same pattern previously written is read back. Shift the pattern to the left by 1 bit (to 0x00000002), repeat the write, read, and compare the cycle. Shift again and repeat until the last writable bit in register N is reached (0x80000000 for a 32-bit register). For example, a 6-bit register is effectively tested with the following patterns: 0x0001 0x0002 0x0004 0x0008 0x0010 0x0020 0x0040 0x0080 0x0100 0x0200 0x0400 0x0800 0x1000 0x2000 0x4000 0x8000 Repeat the steps until all FPGA registers are tested. The BIST test runs to verify the SRAM of the FPGAs. Notes The execution of this command is subject to Admin Domain restrictions that may be in place. Refer to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability" for details. This command is supported only on Brocade FR4-18i blades and Brocade 7500 platforms. Operands This command has the following operands: --slot slotnumber Specifies the slot number on which the diagnostic operates. The default is 0 and operates on fixed-port-count products. -testtype type Specifies the test type to run. By default, the command runs all tests. Valid tests include: 0 All tests 1 DMA test 2 SRAM BIST test -unit number Specifies the FC Router FPGA to test. By default, all FC Router FPGA in the specified slotnumber are used. Valid number values include: 0 FC Router FPGA 0 1 FC Router FPGA 1 2 All FC Router FPGAs Examples To run all tests on slot 7 and FC Router FPGA 1: 162 Fabric OS Command Reference 53-1000599-02
