3.3.13 B6. External SRAM Test

Command: memtest -e
Function: It tests DMA SRAM by performing the tests described in test B1. The Scratch
Pad Test.
Default: Disabled

3.3.14 B7. CPU GPR Test

Command: memtest -b
Function: This test tests the CPU General Purpose Registers. This performs exact the same
way of testing as described in B1 over 3 voltages (1.1V, 1.2V, 1.3V).
Default: Enable

3.3.15 C1. EEPROM Test

Command: setest
Function: An increment test data is used in EEPROM test. It fills the test data into the test
range and read back to verity the content. After the test, it fills data with zero to clear the
memory.
Default: Enabled

3.3.16 C2. CPU Test

Command: cputest
Function: This test opens the file cpu.bin. If file exists and content is good, it loads code to
rx and tx CPU and verifies CPU execution.
Default: Enabled

3.3.17 C3. DMA Test

Command: dmatest
Full the entire host DMA buffer with 32 bytes of FF's and then 32
bytes of 00's.
Full the entire host DMA buffer with all zeros.
Full the entire host DMA buffer with all FF's.
Full the entire host DMA buffer with data 0xAA55AA55.
Full the entire host DMA buffer with data 0xAA55AA55.
