Common Problems and Troubleshooting Strategies During the Development of Forlinx Embedded Allwinner Series SoMs

🚀 Troubleshooting Forlinx Embedded Allwinner SoMs Made Easy

Forlinx Embedded has been collaborating with Allwinner Technology since 2019, launching 7 industrial-grade SoMs like FETT507-C, FETA40i-C, and FET153-S.

During development, engineers often face interface and signal issues. Our practical troubleshooting guide covers:

🔹Power & boot issues – check FEL signals, supply, and reset
🔹I2C / SPI / UART / RS485 communication – ensure correct wiring, pull-ups, and drivers
🔹USB, SDIO, LVDS & Ethernet – verify connections, signal integrity, and impedance
🔹Audio & CAN bus – confirm I2C/I2S communication and matching resistors

With structured troubleshooting, your SoM development becomes faster and more reliable. Learn from our experiences and accelerate your embedded projects!
