https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1471438/tda4vm-remoteproc-errors-when-loading-module

器件型号：TDA4VM

工具与软件：

1.在 SDK10中、REMOTEPROC=y、RPMSG_NS=y 和 RPMSG_virtiio=y 中、正确吗？

2.这意味着我需要构建和加载的模块是：

* TI_K3_R5_REMOTEPROC

* RPMSG_CTRL

* RPMSG_CHAR

3.我按以下顺序加载它们:

ROOT@AS-P-3-340009:~# insmod /lib/modules/6.6.58-ti-01614-g52c7243d3aa4/kernel/drivers/rpmsg/rpmsg_char.ko

ROOT@AS-P-3-340009:~# insmod /lib/modules/6.6.58-ti-01614-g52c7243d3aa4/kernel/drivers/rpmsg/rpmsg_ctrl.ko

ROOT@AS-P-3-340009:~# insmod /lib/modules/6.6.58-ti-01614-g52c7243d3aa4/kernel/drivers/remoteproc/ti_k3_r5_remoteproc.ko

[ 114.739842] k3_r5_rproc bus@100000：bus@28380000：r5fss@41000000：k3_r5_cluster_rproc_init 失败、ret =-517

[114.756315] remoteproc remoteproc0：正在释放41000000.r5f

[ 114.768334] k3_r5_rproc bus@100000：r5fss@5c00000：k3_r5_cluster_rproc_init 失败、ret =-517

[ 114.782663] remoteproc remoteproc0：正在释放5c0000.r5f

[ 114.791826] k3_r5_rproc bus@100000：r5fss@5e00000：k3_r5_cluster_rproc_init 失败、ret =-517

[ 114.803325] remoteproc remoteproc0：正在释放5e0000.r5f

正如您所看到的,我仍然收到这些集群错误,现在我没有在/sys/class/remoteproc 下得到任何 remoteproc*

当我至少有 TI_K3_R5_REMOTEPROC=y 时、我得到了 remoteproc*条目、并且可以加载和运行固件。

我在做什么错？

是的、正确。这些来自上游默认值 默认配置 非常重要。

[报价]
这种顺序是可以的。加载前两个模块时不应出现任何行为变化、因为在初始化 Remoteproc 平台驱动程序之前不会创建 rpmsg 设备。

谢谢苏曼

正如你所想的那样、它被证明是邮箱 DTS 设置。在最后一个 SDK 中、它们在主 DTS 中以隐式方式启用。在 SDK 10中、已在多个位置以及 MCU-WAKEUP DTS 中添加了 status ="已禁用"。

以上操作使我的邮箱无法加载。添加 status ="正常"；成功了。

谢谢！

很抱歉、我们很快就会联系到。

内置 ti_k3_r5_remoteproc 仍然显示了上述情况。这会使 Remoteproc*目录出现、但加载时间比我之前提到的要长2秒。

将 ti_k3_r5_remoteproc 编译为模块：

没有 remoteproc*目录。

我已经检查邮箱配置、没有什么与 common-proc-board dts 不同的地方。

请提供建议。

尊敬的 Jared：

我的设置与您的设置类似、但我们的芯片上没有任何 DSP：s、因此我没有加载任何 ti_k3_dsp_remoteproc 模块。我也没有加载 PRU remoteproc 模块。

我将 ti_k3_r5_remoteproc 列入黑名单、但 modpro探测会提供另一个结果：

root@AS-P-3-340009:~# lsmod

[  153.738330] remoteproc remoteproc0: releasing 5e00000.r5f

此外、即使我也得到错误-517、如果我将其构建为"ti_k3_r5_remoteproc=y"、remoteproc 是否正常工作呢？当构建它并作为模块加载它时,我得到相同的错误,但所有 remoteproc*目录都丢失了:

root@AS-P-3-340009:~# ls /sys/class/remoteproc/ -al
total 0
drwxr-xr-x 2 root root 0 Feb 11 08:41 .
drwxr-xr-x 76 root root 0 Feb 11 08:41 ..

我想到的一个问题是 U-Boot 的版本。我们仍在发布版本2023-04、这会是问题吗？

此致、

我怀疑您的设备树有问题、无论是在内核中还是 u-boot 中。

尊敬的 Jared：

我离得越来越近了。 CONFIG_OMAP2PLUS_MBOX 被设置为"m"但我没有加载该模块。如果我选择将 ti_k3_r5_remoteproc 构建为"y"、我猜该模块将是"y"、这就是我在执行该操作时它如何工作的原因。

现在加载 remoteproc 模块会加载并启动所有主 r5f：s、并且 ping 正在运行：
