`Disk full` when compiling OP-TEE 4.6.0 on `hikey960.xml`

[qianfei11]

I follow the instructions in the document:

repo init -u https://github.com/OP-TEE/manifest.git -m hikey960.xml -b 4.6.0
repo sync -c -j$(nproc)
cd build/; make -j2 toolchains
make -j$(nproc)

After compiling all the software components, the output shows that the boot-img has reached its limit:

...

Is it a bug, or have I missed anything?

Duplicate of OP-TEE/optee_os#7361 ?

[qianfei11]

@jenswi-linaro Thanks for replying.

I looked into the issue#7361, it seems that the compiled output of boot-fat.uefi.img has grown out of the max size of the Hikey960 board's boot section.

Perhaps some optimizations on the size could be made, and further testing on the Hikey960 board would be beneficial?

[jenswi-linaro]

Sure, we'll accept patches.

How to fix this issue for the Hikey 960 platform? @qianfei11 @jenswi-linaro

[qianfei11]

@TaihuLight
Try to compile the Linux kernel with Optimize for size (-Os), which can slightly reduce the image size.

[TaihuLight]

@qianfei11 @jenswi-linaro Does this optimization resolve the issue? If so, how to use the option -Os to change the file https://github.com/OP-TEE/build/blob/master/hikey960.mk?

[jenswi-linaro]

You could try using a larger image.

[TaihuLight]

@jenswi-linaro @qianfei11 @msgilligan @d3zd3z How can I resize the image? Starting from 4.3.0, all versions have this issue when building OP-TEE for Hikey 960. It is a serious bug for employing newer OP-TEE on the Hikey 960 platform. The fixing method shown in OP-TEE/optee_os#7361 (comment) does not work.

[jenswi-linaro]

I don't know. I've never used that platform.
