求助RTX iap 跳转问题
本帖最后由 nstopb 于 2021-4-20 12:26 编辑boot程序跳转功能确认OK 跳转后无法进入main函数，查看内存停在了boot程序的hardfault函数中，于是把boot程序中跳转之前的__set_PRIMASK改为__set_FAULTMASK，跳转后现象变成了 停留在osKernelStart()函数的return __svcKernelStart();有大佬能帮忙吗~~
方便的话，参考我这个试试
分享个基于STM32H7的BOOT和APP代码都使用RTX5的案例，相互之间任意跳转

我跳转的程序应该没有问题。似乎是停在了rtx内核启动函数中。请问__svcKernelStart()函数是做什么的， 右键找不到定义。我是在keil中直接启用的rtx，这部分不开源还是我少添加了文件吗。这个是接手了别人的项目之前的工程应该是keil4建立的， 并且是老版本的RTX，和我新建立的工程某些文件不一致，改了好几天了。rtx有些函数扒不到最底层，找原因实在太难了。。。 MDK5 的以太网组件用过没有 wlx18682353162 发表于 2021-4-20 16:30
MDK5 的以太网组件用过没有
额，没有。。。这和我的问题有关联吗:dizzy: 跳转前，修改为特权级，并清空RAM试试
__set_CONTROL(0); 昨天的问题 终于找到原因了， st和gd的库 定时器中断函数名不一样，本来以为启动文件是cmsis标准 应该统一的，兜兜转转了一天居然发现是这么个小问题。。。。现在任务终于跑起来了，但是os_idle_demon这个空闲中断，优先级却是255，这个会不会有什么问题，请大神或版主能够指导一下，是否需要修改，以及如何修改~~ 谢谢 apleilx 发表于 2021-4-20 16:56

谢谢版主。我后来仔细看了下， IDLE的任务优先级是0，我是看错了。之前跳转进hardfault的问题找到源头了，是我在boot里面启用了systick ，跳转前关闭就正常了。
