Toshiba Electronic Devices & Storage Corporation TC9562 PCIe Ethernet Bridge Firmware

Release Date: March 31 2020 Relase Version: V_1.1.0

===============================================================================

Introduction:

The folder contains a Keil project, which is the firmware for PCIe interface.

Environment:

1. Keil uVision IDE Version 5 or Version 4 is used.
   Evaluation licence should be OK, as the image size is much smaller than 32k. This project does not use any RTOS. It is a OSless firmware.
2. Keil JLink standard/Pro JTAG connector is used.

Procedures

1. Open the project file, compile it and run it.
2. A binary file will be generated, and it is located at ./InOut
3. A windows tool may be used to convert the binary into header file format. If windows environment does not support this tool, please ignore this step.

Notes

1. In general, this OSless Version of firmware is configured to switch from PCIe HW sequencer to PCIe SW sequencer on POR sequence. #define TC9562_SWITCH_HW_TO_SW_SEQ macro is enabled

   In case switch from PCIe HW sequencer to PCIe SW sequencer is not required, it can be disabled #define TC9562_SWITCH_HW_TO_SW_SEQ macro is disabled

2. Some debugging counters are available: #define TC9562_M3_DBG_CNT_START 0x2000F800 // Debugging count SRAM area start address /* TC9562_M3_DBG_CNT_START + 4*0: DMA TX0

   • .........................
   • TC9562_M3_DBG_CNT_START + 4*5: DMA TX5
   • TC9562_M3_DBG_CNT_START + 4*6: DMA RX0
   • .........................
   • TC9562_M3_DBG_CNT_START + 4*11: DMA RX5
   • TC9562_M3_DBG_CNT_START + 4*12: INTC WDT Expiry Count
   • TC9562_M3_DBG_CNT_START + 4*13: MAC LPI/PWR/EVENT
   • TC9562_M3_DBG_CNT_START + 4*15: guiM3Ticks */

3. Firmware Version #define TC9562_M3_DBG_VER_START 0x2000F900 // Firmware Version SRAM area start address
