【FAQ】烧录sof时报错External hardware access error

BOB_Sun

Q：用Quartus Pro 24.1烧录自己的.sof时，报错提示Device has stopped receiving configuration data；External hardware access error. (Subcode 0xC80E, Info 0x00000007, Location 0x00001800)；The first I2C command has failed, no response from Voltage Regulator。烧cd里demo的sof都可以成功。


A：检查下工程的.qsf文件是否有VID Assignments，可以直接把cd-rom/Demonstration/FPGA/golden_top/Agilex_SoM.qsf里的VID Assignments复制到自己工程的.qsf里，然后编译工程生成.sof再烧录试试。
