在docker(ubuntu:20.04)中编译时, facebuildercmd出现段错误;
换成了一台Ubuntu 22.04.2 LTS(Linux tao 5.15.0-58 x86_64 GNU/Linux)物理机编译成功;
原因待查

R328-S1有原厂的 FreeRTOS SDK，具体可以与FAE沟通开案

@ivan_wan 确实，linux编译环境下打包脚本对应的是pack_img.sh。这个值应该是通过envsetup.sh里function pack()传进去的。source melis-env.sh 会调 envsetup.sh，然后调pack_img.sh。pack时可以加 -a [type] 指定存储介质，不然就是使用function pack()里默认的nor。

Any update on the source code? I have downloaded d1_freertos_20211105_4.rar.

I have done an independent version, pretty much came to the same results as here. All tick timer stuff works fine using CSR time and MMIO MTIMECMP. The comments about 'stability' bother me, mine runs for hours and hours doing simple stuff.

While working on my drivers for UART, TMR, SPI, etc. I always start with POLLING, then do INTERRUPT, then do DMA (where needed). All my polling stuff works fine. I can't get ANY of my interrupt stuff to work. My main problem is that I can't get ANY of the Peripherals to trigger the PLIC_IP registers to even initiate an External Interrupt to the CLINT. I've checked enables, priorities etc. Think I have them all set correctly.

I downloaded this version because it looked like it had some interrupt stuff in it. After searching through all the source code with a fine tooth comb I can only find the 'potential' for the interrupt, never a call from driver or application code to enable/use it.

Has anyone done any external interrupts (TMR or UART) in a FREERTOS Bare Metal environment?

Is there some secret mux or clock enable to get the TMR peripheral to connect to the PLIC to connect to MEI of CLINT? OpenSBI does enable the RISCV_CFG_BGR registers and I had hopes that would be the missing link, but it didn't fix it. MXSTATUS for Supervisor Delegation etc. isn't needed since FREERTOS runs in Machine mode. Any other suggestions?

Of course Linux/Tina must use interrupts but I've searched for hours in source code and can't find anything. Could be buried deep in the DTS.

git clone 源码，别下载zip，zip会改权限路径

@caozilong 他这里应该要给我引用这个头文件才对

不知道为什么会给我引用到这个路径的头文件去了

@whycan 谢谢，按照你说的都可以成功了！

@huangwc
ID 读成 0 0，原因找到了，flash 芯片没焊好。。。
但还是烧录失败.

请问用的是啥wifi模组呢？

@caozilong
非常好的文章，想请教一下有什么工具或者方法对死锁问题进行debug吗

@whycan 在 如果不按文档走，迟早要翻车，这不melis就翻了 中说：

按套路走，搞定。
msys卡壳了，

不知道 cygwin 是如何解决这个 8192超长命令行问题的?

@pcmxz 在 V833@Melis4.0 开发QuckStart 中说：

终于把melis上支持ap6212/ap6181的驱动搞稳定咯，melis什么时候把自带的ap6203开源啊？

👍 望分享模组集成的过程，让坛主给你加鸡腿😃
