[参考译文] TDA2SX：基于 MMWCAS-DSP-EVM 板的电路、TDA2X 芯片设计无法引导、内核未加载

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1321554/tda2sx-circuit-based-on-mmwcas-dsp-evm-board-with-tda2x-chip-design-unable-to-boot-kernel-not-loading

您好、Champs：

硬件：基于  MMWCAS-DSP-EVM 的自有电路板、除了添加 UART 功能外保持不变
SW：PROCESSOR_SDK_VISION_03_07_01_00

客户 尝试使用 TDA2X 芯片根据 MMWCAS-DSP-EVM 板电路来重建开发板电路。 当前使用的配置是 tda2xx_CASCAFE_LINUX_RADAR 版本。 当他将开发板连接至计算机时、串行端口显示内核未加载。

下图是定制电路板的串行输出与 MMWCAS-DSP-EVM 输出的对比。 您能否建议如何修改配置文件以使系统能够正确引导？ 是否有必要刷写板载 EEPROM？

谢谢
