[参考译文] TDA4VM：使用 TVM 导出 TIDL 模型、使用 DLR 推理显示无法加载 DLR 模型

有时、，错误消息是

[C7x_1 ]  17278.755664 s: Could not Allocate memory for memtab 7 of size 330552060 in 17
[C7x_1 ]  17278.755694 s: init_tidl_subgraph: alloc_mem_records failed

有关"export TIDL_RT_DEBUG=3"的更多详细错误信息：

/* DDR for c7x_1 for local heap [ size 256.00 MB ] */
#define DDR_C7X_1_LOCAL_HEAP_ADDR (0x100000000u)
#define DDR_C7X_1_LOCAL_HEAP_SIZE (0x10000000u)

在 File、 vision_apps/platform/j721e/rtos/app_mem_map.h 中、我看到"DDR for c7x_1 for local heap [大小为256.00 MB ]"。 那么、我可以将其修改为1024MB 以部署我的模型吗？ 或者还有其他方法可以部署我的模型？

可以、可以修改存储器映射。  以下是 PSDK RTOS 中有关此主题的开发人员手册：https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_02_00_05/exports/docs/psdk_rtos/docs/user_guide/developer_notes_memory_map.html 

我修改了相关文件、但仍然无法为超过256MB 的内存分配内存、我的步骤如下：

1.修改 文件 gen_linker_mem_map.py 中的 DDR_mem_size_hi =1*GB

2. Python  gen_linker_mem_map.py、将生成 K3-j721e-rtos-memory-map.dtsi 和 c7x_1

3. 重建 DTB 并安装到 SD 卡中

4.修改 My project 中包含 linker_mem_map.cmd、 j721e_linker_freertos.cmd、 main.c、 app_mem_map.h 的相关文件

然后编译我的项目并在 TDA4VM 中运行。

那么、我想知道是否有更详细的步骤要遵循？ 在 c7x_1文件中、生成了其他文件。 有必要的话？

将上载编译器所需的文件和 dtsi。

e2e.ti.com/.../k3_2D00_j721e_2D00_rtos_2D00_memory_2D00_map.dtsi.zip

Yongchao、
不能分配内存时是否有相同的日志？

我使用此 SDK ti-processor-sdk-rtos-j721e-evm-08_02_00_05进行尝试、似乎是正常的

首先、您需要在 RTOS SDK 上进行修改

您好、Yongchao、

  只是想给你另一个数据点，除了康佳所说的。

  我针对 C7x 测试了以下存储器映射、将暂存堆从368MB 缩小到112MB、将本地堆从256MB 增加到512MB、以便我保持"DDR_mem_size_hi"不变。  "DDR_mem_size_hi"需要反映暂存堆和本地堆的总大小。  请参见差动。

  然后在 vision_apps 中重建 SDK 并安装更新的 Linux 文件系统。

  您可以验证 c7x 固件映射文件中的更新更改：

vision_apps$ head -n 30 out/J7/C71/FREERTOS/release/vx_app_rtos_linux_c7x_1.out.map | tail -n 5
  DDR_SHARED_MEM        0000b8000000   20000000  00000000  20000000  RWIX
  DDR_C7X_1_SCRATCH     000100000000   07000000  07000000  00000000  RWIX
  DDR_C7X_1_LOCAL_HEAP  000107000000   20000000  20000000  00000000  RWIX

  "DDR_mem_size_hi"需要反映在器件树中的整个系统映射中。  请注意"shared-dma-pool"中的大小"0x27000000"、起始地址为0x8_8000_0000。  因此、有关重新编译 dtbs 的说明。

        vision_apps_core_heaps_hi: vision-apps-core-heap-memory-hi@880000000 {
                compatible = "shared-dma-pool";
                reg = <0x08 0x80000000 0x00 0x27000000>;
                no-map;
        };

  由于我保持"DDR_mem_size_hi"的整体不变、因此我不需要更新 EVM 目标文件系统上的现有 dtbs。  如果修改了总大小、请在 dtsi 文件中进行相应更改、重新生成 dtbs、然后复制到您的 EVM。  重新启动。

  您可以通过查看/proc/iomem 来验证 EVM 上刻出的"共享 DAM-POOL "区域。  如果您修改了 C7x 的总"DDR_mem_size_hi"、则应在重建 dtbs 后在此处反映。

# cat /proc/iomem | grep 880000000
880000000-8a6ffffff : reserved

  希望这对您有所帮助。

在修改 dtsi 并重新构建 visionapp 后、我仍然无法分配1G 内存、并且我使用 vision_app basic_demo app_mem 进行 alloc mem 测试 ，错误消息如下，每次在 APP_MEM_HEAP_DDR 中执行350MB 的 alloc 操作。 它只成功了一次。

#ddr_mem_size_hi = 256*MB;
ddr_mem_size_hi = 1*GB;

我将其修改为1GB、然后运行 python gen_linker_mem_map.py、然后更新 dtsi

在我的器件中、我检查 DDR_LOCAL_HEAP 是否已由更新  

root@tda4vm-sk:/opt/out/J7/A72/LINUX/release# hexdump /proc/device-tree/reserved-memory/vision-apps-core-heap-memory-hi@880000000/reg

0000010

40xxxxxx 意味着1G 用于 DDR 本地堆。

然后、我使用 make vision_apps -J4构建 vision_apps、它将生成 ./vx_app_arm_mem.out 文件。

然后、我在 TDA4VM 器件中对输出文件执行 Coye 操作并运行 ./vx_app_arm_mem.out 、该消息如上所示。

我堆叠文件 .../../../FreeRTOS/release/vx_app_rtos_linux_c7x_1.out.map
