Redstorm:JTAG Interface

From OSR

Using JTAG interface

• rsh to the L0 for the node (slot = int(node/4), module=int(node%4))

   rsh -l root cx24y2c0s1

• Use hdt to dump the registers from module 0

   [Compute(24,2,0.1)]# hdt -n 0 -r 0:10
   00 0x0000000000000011 # rax
   01 0x0000000011000312 # rcx
   02 0x0000000000000cfc # rdx
   03 0x000000000000001c # rbx
   04 0x0000000000000000 # rsp
   05 0x0000000000000000 # rbp
   06 0x0000000000ff8003 # rsi
   07 0x0000000000000000 # rdi
   08 0x0000000000000007 # eflags
   09 0x000000000000f3e6 # rip

• Use hdt to dump physical memory

   hdt -n 0 -d 0x100000:1024
