Explaination

Loaders are used for loading other modules.

Commonly found in CoreOS and Flash.


Known loaders

Loader Location Type Remarks
bootldr Flash Boot Loader primairy loader from chain of trust
metldr Flash Meta Loader aka asecure_loader. Loads other loaders
appldr CoreOS Application Loader loads vsh.self (Userspace Module)
isoldr CoreOS Isolation Loader loading isolated SPU modules
lv1ldr CoreOS Hypervisor Loader loads lv1.self (Hypervisor)
lv2ldr CoreOS Supervisor Loader loads lv2_kernel.self (Supervisor kernel)

Stop Codes

Stop Code Module Remark
0x30 isoldr Version mismatch (isoldr version differs from version returned by SPU channel 73).
0x16 isoldr

isoldr asks for the version in two chuncks, if you want to pass version 3.41 (0x0003004100000000)

//for ch_73_round_0
data0 = 0x00030041;
//for ch_73_round_1
data1 = 0x00000000;

isoldr

Used for loading isolated SPU modules.

LS Parameters layout

Address Usage Comments
0x3E000 Wait flag If (flag==0){wait;} // use 0xFF00000000ULL
0x3E400 EID0
0x3E800 Arguments
0x3EC00 QA-Token If not used set to -1
0x3F000 Program revoke list

Arguments

Depending which isolated module you want to load, you would need to pass it different arguments.
