请教，使用rtt studio自动生成的驱动文件，pwm_config.h中没有pwm1和pwm8的配置定义。查了下芯片手册，这两个是高级定时器，寄存器定义和普通的不同，是因为这个原因吗？那是需要自己手动写bsp还是定义在了其他地方？

几处未知原因的rtthread utest问题

4

我使用GD32F103RCT6开发板移植STM32的相关BSP，在UTEST中遇到几个问题，其中部分已提交PR，另外几处确实不熟悉原因： 1. mailbox_tc.c中，thread3_recv_dynamic_mb，result = rt_mb_recv(test_dynamic_mb, (rt_ubase_t *)&mb_recv_str2, RT_WAITING_FOREVER);，会在第二次运行utest时失败，打断点发现在ipc.c:2318行，rt_schedule();行失败，然后线程返回错误。 2. thread_tc.c中，test_thread_suspend函数，会在此test case中，使用rt_thread_suspend中断其它线程，但看上去rt_thread_suspend是不允许其它线程中断的，因RT_ASSERT(thread == rt_thread_self());约束 还请大佬们指教
