器件型号：PHYTC-3P-KIT-AM64

工具与软件：

各位专家、您好！

我已经按照指南( www.ti.com/.../6284567407001 )实现了 IPC_RPMSG_CHAR 示例。 即使在更新 R5F 固件后、我也会收到以下错误： 

root@phyboard-electra-am64xx-2:examples# ls
Makefile  Makefile.am  Makefile.in  README  rpmsg_char_simple  rpmsg_char_simple.c  rpmsg_char_simple-rpmsg_char_simple.o
root@phyboard-electra-am64xx-2:examples# rpmsg_char_simple -r 2 -n 3
_rpmsg_char_find_ctrldev: could not find the matching rpmsg_ctrl device for virtio1.rpmsg_chrdev.-1.14
Can't create an endpoint device: Invalid argument
TEST STATUS: FAILED
root@phyboard-electra-am64xx-2:examples#

如何解决这一问题？

BR、

Akash
