[参考译文] PROCESSOR-SDK-AM57X：大数据 IPC 示例无法运行 dma-buff、并在 SDK 9.03 中删除了 SDK 规则

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1538827/processor-sdk-am57x-big-data-ipc-example-fails-to-opem-dma-buff-and-make-rule-for-sdk-has-been-removed-in-sdk-9-03

工具/软件：

您好：

我目前正在执行大数据 IPC 示例的 RTOS SDK 发行说明中列出的说明。 我目前正在开发 am57x BeagleBoard-x15。

我按照这里列出的说明进行操作： https://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/09_03_00_00/exports/docs/rtos/index_examples_demos.html#how-to-run-the-example 

以下日志显示了我遇到的错误：

如您所见、我已成功将 simple_buffer 固件链接到 dsp1。 当我尝试托管新固件时、我遇到了“Failed to open DMA-BUF“错误。

然后、我尝试按照此处列出的说明重新编译工程： https://software-dl.ti.com/processor-sdk-rtos/esd/AM57X/09_03_00_00/exports/docs/rtos/index_examples_demos.html#how-to-re-build-the-example

在运行“make big-data-ipc-demo“命令时、我遇到了以下问题：

jsava@laptop-183:/export/home/jsava/ti-processor-sdk-linux-am57xx-evm-09_03_06_05$ make big-data-ipc-demo

看起来大数据配方已安装到文件系统中、但在 SDK 9.03 中删除了 make 规则

请告诉我、我是否要搞砸任何步骤。 感谢您的帮助！

此致、
