It says under heading Syscalls (via syscall instruction) that "Currently only syscall 0x04 is still used in production versions of IOSU."
This does not seem correct. I see several other Thumb SysCalls still in use on FW 5.5.x (15702)
Example:
IOS_KERNEL:08133F44 Call_IOS_KERNEL__sys_close
IOS_KERNEL:08133F44 LDR R12, =(__sys_close+1)
IOS_KERNEL:08133F48 BX R12 ; __sys_close
IOS_KERNEL:08133F4C off_8133F4C DCD __sys_close+1
IOS_KERNEL:08133F50 Call_IOS_KERNEL__sys_open
IOS_KERNEL:08133F50 LDR R12, =(__sys_open+1)
IOS_KERNEL:08133F54 BX R12 ; __sys_open
IOS_KERNEL:08133F58 off_8133F58 DCD __sys_open+1
IOS_KERNEL:08133F5C Call_IOS_KERNEL__sys_read
IOS_KERNEL:08133F5C LDR R12, =(__sys_read+1)
IOS_KERNEL:08133F60 BX R12 ; __sys_read
IOS_KERNEL:08133F64 off_8133F64 DCD __sys_read+1
IOS_KERNEL, BOOT1, IOS_MCP, IOS_NIM_BOSS all use more than just 0x04, __sys_write0
Unless otherwise challenged as to why not, I will update the tables to correct this [[User:Datalogger|Datalogger]] ([[User talk:Datalogger|talk]])
