In this post, I will explain an example of batch firmware download and operation testing for five WIZ750SR modules from WIZnet using the testX Flasher and a single interface board.<\/p>\n\n\n\n

First, you need to know the pinout of the WIZ750SR module in order to configure the connection with the testX Flasher.<\/p>\n\n\n\n

As shown in the diagram, many pins are provided, but the pins related to firmware download are the power (VCC, GND), BOOT, RSTN, U_RXD2, and U_TXD2, totaling six pins. Additionally, to verify that the firmware operates correctly after the download, the RXD and TXD pins for data communication are also used.<\/p>\n\n\n

To easily connect the testX Flasher TWF-100 with the user's target board, Twarelab offers the testX Flasher Interface board as an option.<\/p>\n\n\n

For detailed specifications, please refer to the separate document.<\/p>\n\n\n\n

The interface board provides connectors for connecting five target boards, and the connectors for the target boards have the following pinout.<\/p>\n\n\n

Pin connections between the Interface board and the Target board<\/h1>\n\n\n\n
    \n
  • The ISP (In-System Programming) port of the W7500(P) MCU used in the WIZ750SR is connected to U2_RXD and U2_TXD. Connect it to one of the UART ports on the Interface board.<\/li>\n\n\n\n
  • Connect the BOOT pin and RSTN pin of the WIZ750SR to the GPIO pins on the Interface board.<\/li>\n\n\n\n
  • Connect the RXD and TXD pins for data transmission and reception to another UART port on the Interface board.<\/li>\n<\/ul>\n\n\n\n

    According to the above criteria, the pin connections are as follows.<\/p>\n\n\n

    Test Procedure (Test Set)<\/p>\n\n\n\n

      \n
    • Power on the WIZ750SR via control of the eFuse module on the interface board.<\/li>\n\n\n\n
    • Reset the WIZ750SR using control of the RSTN pin.<\/li>\n\n\n\n
    • Enter W7500 Boot Mode by controlling the BOOT and RSTN pins.<\/li>\n\n\n\n
    • Erase existing data in the flash memory.<\/li>\n\n\n\n
    • Download the specified firmware.<\/li>\n\n\n\n
    • Reboot using control of the RSTN pin<\/li>\n\n\n\n
    • Check the messages coming from the WIZ750SR U_TXD2 pin using U2_RXD to verify if it is booting correctly.<\/li>\n\n\n\n
    • Send AT commands to the WIZ750SR using U1_TXD.<\/li>\n\n\n\n
    • Check the responses from the WIZ750SR using U1_RXD.<\/li>\n<\/ul>\n\n\n\n

      If there is a response timeout or if the expected value is not received at any step in the procedure, consider it a failure.<\/p>\n\n\n\n
