thanks that repo would be useful, I notice that both Keil_core and IAR_Core within the cmsis is the same, without any file differences. you should just have it as CSMSIS/Core https://github.com/zhangslice/mm32sdk/tree/main/mm32f327x/CMSIS

do you want to merge them together ? I am fine If you still want to keep it that way though.

[zhangslice]

OK, because the syntax of IAR and Keil is different in some places, the reason why they are divided into two folders is that sometimes we will rewrite them, I will delete one of IAR later   ------------------ 原始邮件 ------------------ 发件人: "hathach/tinyusb" ***@***.***>; 发送时间: 2021年6月2日(星期三) 下午2:14 ***@***.***>; ***@***.******@***.***>; 主题: Re: [hathach/tinyusb] Add MM32 SDK and USB driver (#869) The following repository can be used, and the SDK will be updated if there are any updates or additions https://github.com/zhangslice/mm32sdk thanks that repo would be useful, I notice that both Keil_core and IAR_Core within the cmsis is the same, without any file differences. you should just have it as CSMSIS/Core https://github.com/zhangslice/mm32sdk/tree/main/mm32f327x/CMSIS do you want to merge them together ?

Ok thanks for letting me, in general you should not modify those file since they are from ARM which already taken care of the keil/gcc/iar. But that is up to you.

[zhangslice]

Well, thank you, that's a good suggestion

I pushed the update to your master branch on your fork, please pull before making any other commit and update. There are 2 requests for change as follows:

• MIT license is required for dcd_mm32f327x_otg.c
• tinyusb_keil.zip must be removed

Note: I have to mm32sdk under the company name just in case you guy makes more family than mm32. This could slightly changes the compiling and include path from your project file.

[hathach]

The port still need bsp to verify that mcu work with existing project on mm32. However, it is good as intial PR.

Note: I have removed the keil project .zip, such as binary file is not allowed in this repo. You could probably provide it as additional, add-on to your sdk.
