Add correct check for parameter count. This fixes this issue when `hash` cmd is invoked without params: => hash data abort pc : [<bf739204>] lr : [<ba6effa8>] reloc pc : [<60019204>] lr : [<5afcffa8>] sp : ba6dd9c8 ip : bf7391f0 fp : bf74ec14 r10: 00000001 r9 : ba6dfea0 r8 : bf7ea030 r7 : 00000000 r6 : ba6effa8 r5 : 00000000 r4 : ffffffff r3 : bf7c257c r2 : 00000001 r1 : 00000000 r0 : bf7e6e34 Flags: nZCv IRQs off FIQs on Mode SVC_32 Code: e5934004 e1a0e003 e59f3050 e2444001 (e5f4c001) Resetting CPU ... resetting ...
