LSDK1906 has problems with compiling Edgescale firmware

[pengluo]

Hello

I am getting an error when compiling Edgescale firmware using LSDK1906. Executing ‘flex-builder -m ls1046ardb -a arm64’ can be done before opening Edgescale.

However, after opening Edgescale, the operation of ‘flex-builder -m ls1046ardb -a arm64’ will cause an error. The specific operations are as follows:

1,gedit configs/build_lsdk.cfg ：

         CONFIG_APP_EDGESCALE=n   ------>   CONFIG_APP_EDGESCALE=y

         #SECURE_PRI_KEY=/path/srk.pri  ------->  SECURE_PRI_KEY=/path/srk.pri
         #SECURE_PUB_KEY=/path/srk.pub -------> SECURE_PUB_KEY=/path/srk.pub

2,flex-builder clean

3,flex-builder -m ls1046ardb -a arm64

.......

error:

Can you advise me what to do next?

Hello Peng Luo,

There is no valid srk.pri and srk.pub key pairs in /path folder.

You could go to cst folder, then generate srk.pri and srk.pub key pairs, then copy them to a specified path.

Please refer to the following example.

$ cd  ~/flexbuild_lsdk1906/packages/apps/cst
$ ./gen_keys 1024

$ cp /home/yiping/flexbuild_lsdk1906/packages/apps/cst/srk.pri  ~/flexbuild_lsdk1906
$ cp /home/yiping/flexbuild_lsdk1906/packages/apps/cst/srk.pub  ~/flexbuild_lsdk1906

Then modify configs/build_lsdk.cfg as the following

SECURE_PRI_KEY=//home/yiping/flexbuild_lsdk1906/srk.pri
SECURE_PUB_KEY=//home/yiping/flexbuild_lsdk1906/srk.pub

Then execute flex-builder command

$ flex-builder -c cst -m  ls1046ardb

$ flex-builder -m ls1046ardb -a arm64

Thanks,

Yiping
