78Q8430 ARM9(920T) Linux Driver Diagnostic Guide UG_8430_003 1 Introduction The Teridian Semiconductor Corporation (TSC) 78Q8430 is a single chip 10/100 Ethernet MAC and PHY controller supporting multi-media offload. The device is optimized to enhance throughput and offload network protocol tasks from the host processor for demanding multi-media applications found in Set Top Boxes, IP video, and Broadband Media Appliances.
UG_8430_003 78Q8430 ARM9(920T) Linux Driver Diagnostic Guide 2 System Requirements 2.1 Hardware Requirements The following list describes the minimum hardware requirements for the 78Q8430 ARM9 Linux based evaluation and testing platform: • • • 2.2 78Q8430 Embest Evaluation Board (daughter card). The Embest ARM9 S3CEB2410 evaluation platform (also called the ARM Board in this document).
78Q8430 ARM9(920T) Linux Driver Diagnostic Guide UG_8430_003 3 Diagnostic Tools The 78Q8430 10/100 Ethernet MAC/PHY Linux device driver provides extensive configuration support through its IOCTL interface. The 78Q8430 is a uniquely feature rich ethernet solution. As such, the standard Linux ethernet configuration applications, ethtool and mii-tool, do not address the majority of the available features.
UG_8430_003 78Q8430 ARM9(920T) Linux Driver Diagnostic Guide 4 Diagnostic Procedures The test procedures use the target Embest platform under test (containing the 78Q8430) and a Linux Host PC, which generates the majority of the tests and provides some required verification facilities. The test procedures are preceded by the Test Setup section describing the preparation needed for using the testing platform. The test procedures are generally grouped by 78Q8430 features.
78Q8430 ARM9(920T) Linux Driver Diagnostic Guide UG_8430_003 9. When boot up completes, enter the following at the prompt: arp -s 192.168.10.100 00:0E:2E:5B:25:86 10. On the Linux Host, issue the following ping command to verify the connection to the target: ping 192.168.10.99 4.3 Packet Tests This test group drives TCP/IP generated ping packets from the Linux host to the target containing the 78Q8430 board under test, and vice versa. 4.3.
UG_8430_003 4.4.3 78Q8430 ARM9(920T) Linux Driver Diagnostic Guide Software Reset The procedure generates and verifies the software reset. 1. Attach and configure a Logic Analyzer to trap access to register 0x154 (TP2 and TP5, refer to the 78Q8430 Embest Evaluation Board User Manual). 2. Enter the command: 8430-tool eth0 –R 3. Verify that the MAC Reset bit has been written to the 78Q8430. 4.4.4 EEPROM Access This procedure tests random EEPROM read and write access. 1. 2. 3. 4. 5. 6.
78Q8430 ARM9(920T) Linux Driver Diagnostic Guide 4.4.6 UG_8430_003 Append CRC 1. On the Linux host enter: ping 192.168.10.99 2. Verify that the ARM target responds to the pings. 3. Enter the command: 8430-tool eth0 -F crc fix on Note: CRC append and fix are mutually exclusive. CRC append is the startup default. 4. Verify that packets are no longer returned. 5. Enter the command: 8430-tool eth0 -F crc append on 6. Verify that packets are returned again. 4.4.7 1. 2. 3. 4. 5. 6. 7. 8.
UG_8430_003 78Q8430 ARM9(920T) Linux Driver Diagnostic Guide 4.4.11 RMON Rollover This procedure verifies the generation of the RMON rollover message. 1. On the Linux host, enter: ping -f 192.168.10.99 2. Verify that the ARM target responds to the pings. 3. On the ARM target, turn on TOE mode by entering the following command: 8430-tool eth0 -T on 4. Run continuously for 1 or more hours. 5. On the ARM target, verify that the RMON rollover message is received. 4.4.
78Q8430 ARM9(920T) Linux Driver Diagnostic Guide UG_8430_003 6. Enter the command: 8430-tool eth0 -P threshold 25 The value 25 is arbitrary; it is a count of blocks, so any value up to 120 is acceptable. 7. On the Linux host: a. Enter: tcpdump -lnei ethN b. Enter: pktgen.sh c. Verify that Pause frames are issued. 8. On the Linux host: a. Kill pktgen.sh b. Enter: ping 192.168.10.99 c. Verify the ping response.
UG_8430_003 78Q8430 ARM9(920T) Linux Driver Diagnostic Guide 4.4.17 OnNow WOL 1. Enter the command: 8430-tool eth0 -L onnow set 0x10203040 0x50607080 0x90A0B0C0 0x00000CD1 2. Enter the command: 8430-tool eth0 -c dump 0x15 6 3. Verify that the stored CAM values make up the group: 0x403080705090. 4.4.18 HNR Frame 1. Enter the command: 8430-tool eth0 -H set 0x000e2e61 0x91790001 0x02030405 0x08004500 0x001e0009 2. The 8430-tool will now be in interactive mode.
