I used RTL8721csm board to test TizenRT rtos, I enter a question. list below

From rtl872x0csm spec, there is no 0x0E000000 address, but the ld script set KM4 IMAGE address 0x0E000000, I don't understand that why can use this address.

https://github.com/Samsung/TizenRT/blob/master/build/configs/rtl8721csm/scripts/rlx8721d_img2_ns.ld#L83

TizenRT is loaded in KM4 region. It has 0xE........ address.

Yes, I see,the problem is that it will trigger a bus fault, PC is 0x0e0013a6, I further debug and found that a bus fault t occurred during IPC sendrequest, I used to command "make download ALL" to download image. I don't know how to compile KM0.Is it related to the lack of KM0 image. Thanks for your reply

[sunghan-chang]

I don't know how to compile KM0.

We use prebuilt KM0, not to dynamically compile.

Is it related to the lack of KM0 image.

I don't think so. Your codes cause the issue. There is no issue on current version with RTL8721CSM.
We usually meet a busfault with null dereference.

Which defconfig are you using? I used cxxtest. My test steps below list:

./tools/configure.sh rtl8721csm/cxxtest
make
make download ALL port=ttyUSB0

I can use the defconfig you tested to verify if there are any issues.

Ok.
@prabu-r Could you check rtl8721csm/cxxtest?

[abhishek-samsung]

Hello @Jan9401 , we have verified it on our side with the same config (rtl8721csm/cxxtest) on the latest commit (846ea71) and there is no issue.

@Jan9401, could you please share the toolchain version being used? Could you also please share the details of the board being used? We also support build using docker (https://hub.docker.com/r/tizenrt/tizenrt) and it can be triggered using ./dbuild.sh menu. If possible could you please try the build with docker?

My gcc version :gcc version 10.3.1 20210824 (release) (GNU Arm Embedded Toolchain 10.3-2021.10).
I used to RTL8720csm board, In theory, there should be no other difference between 8720csm and 8721csm except for the pins, But I saw log, I found that there were still differences in FLASh( Manufacturer : 161 memory type : 64 capacity : 23) . can you share your toolchain and complete testing steps?

[sunghan-chang]

@Jan9401 We use ARM GCC 6.3.1, but we recommend to use docker instead of using ARM GCC directly. (TizenRT docker image contains it) Testing steps are just building, downloading and booting. That's it. After installing the docker, you can use it through ./dbuild.sh menu at os folder. Please refer https://github.com/samsung/tizenrt#environment-setup.

I download ARM GCC 6.31, I foud that there is no issue.I am not familiar with gcc, so I am not sure how this bus fault was generated.

[Jan9401]

I encountered another issue, I entered reboot and prompted 'All OTA addresses not valid, recovery failed'.

[sunghan-chang]

@Jan9401 It's impossible to give any guidance with this information. Could you leave your logs?

Because of that, we provide a script to use the TizenRT docker. When you use it, you don't need to install any tool including ARM GCC. When we update a version of installed tool or request a new tool installation, you can do that with docker version change (And docker version change will be done by our script.).

I would like to know the type of the flash you are using. such as which vendor.
