Gần đây mình bị reboot loop modem này, mở ra xem debug thử xem bị sao. Khi tháo ra thì board như thế này
Nhìn qua bảng mạch một chút thì mình phán đoán các chân UART và JTAG là 2 chỗ mình vẽ trong khung vàng gần các cổng RJ45, UART bên trái, JTAG bên phải. Trong bài viết mình chỉ đề cập tới UART vì mình cũng không có đồ để debug JTAG.
Dùng đồng hồ đo điện đo một chút thì nhân diện được các chân ở UART như sau:
| 1 (tận cùng trái) | 2 | 3 | 4 | 5 |
| 3.3V | TX | GND | RX | 3.3V |
Dùng Putty với baud rate là 115200, mình nhân được boot log như thế này:

Đọc log ở đoạn cuối thì có exception dưới kernel do process ifconfig, dẫn đến kernel panic làm modem tự reboot lại. Mình có cố thử vài command như stopreboot,… nhưng không hiệu quả. Xem kỹ board thì thấy dùng flash SPI NAND MXIC MX35LF2GE4AB, mình không có đồ để đọc dữ liệu chip nên mình đành bỏ…
Cách để nhập được command khi modem khởi động là khi boot xong vào GponCLI thì nhập lệnh enable để có thể dùng lệnh. Còn nữa là khi boot lên có đoạn waiting for your select … mình có thử nhấn vài phím và tổ hợp như “KEY”, Ctrl + C, Ctrl + A,… nhưng không thể ngắt được luồng boot của modem.
