Description

This is the list of SD cards currently tested on Zynq UltraScale+ MPSoC.

Solution

The scope of testing is to test that MPSoC works correctly with different SD Cards.

This is a brief description of the tests performed using an SD1 Controller on a ZCU102 board.

Xilinx System-level testing (Speed Modes covered: Default Speed, High Speed, UHS-I)

1. Default speed at 25 MHz Bus width 1
2. Default speed at 25 MHz Bus width 4
3. High speed at 50 MHz Bus width 1
4. High speed at 50 MHz Bus width 4
5. UHS modes SDR12, SDR25, SDR50, DDR50, SDR104 with width 4
6. Randomize all above modes and frequencies

Standalone (Speed Modes covered: High Speed, SDR)

1. Initialize SDIO controller
2. Initialize SD/MMC device
3. Send Erase, write and read commands to SD/MMC device
4. Validate raw data read from device
5. Bus width tested 1bit/4bit

Boot (Speed Modes covered: Default Speed)

1. Initialize SDIO controller
2. Initialize SD/MMC device
3. Controller Ref Clock 33.33MHz, baud div 4, Interface Clock 8.33 MHz
4. Read Boot image
5. Bus width tested 4bit
6. Tests include boot until Linux with FSBL->ATF->Uboot->Linux in non-secure mode

Linux (Speed Modes covered: High Speed, UHS-I (SDR 104))

1. Bonnie++ (performance test): Performs sequential file write and read test. File size will be double the ram (DDR) size
2. Fdisk: Create the partitions and format the partitions
3. Raw Read/Write test using DD commands: Perform raw read and write test for various sizes starting from 1MB to 250MB
4. Read/Write test using file system: Perform raw read and write test for various file sizes starting from 1MB to 250MB. It also includes mount and unmount test.
5. Hdparm test: Performance test. It reads data from the SD card and measure the throughput.
