Thanks tv84 for your help! My XXTEA_KEY did have an occurrence of a 00 and was generating invalid keys until tv84 took a look and was able to get me a valid unlock key. |

After much reading I have some questions. 1) The modified fw method described by the user Daruosha would apply to this unit? Reading some more I understood it's for DS and Plus is actually an MSO. I gues DS1074Z PPLUS is actually an MSO1074Z, is it right? --- End quote --- Yes. The MSO1074Z comes with the logic probes included. The DS1074Z Plus does not. Only difference is the branding. |

I have been trying to get a memory dump of my DS1074Z-S Plus through the JTAG port having given up getting a back level firmware loaded to access via SCPI on the LAN. I hesitate to ask here, but I am at my wits end. I have learned a great deal about OCD, JTAG access, etc in the many days I have dedicated to this endeavor. And am grateful for the all the great information especially on EEVBLOG which has allowed me to make the progress I have. Using SiSpeed dongle with FT2232 with TMS/TCK/TDI/TDO and RST. RST is connected to SRST on the 1074Z. There is only the one reset signal, so I have to soft reset the TAP. I seem have the interface signals defined correctly (finally!) as I can reset the scope with a reset command, and jtag arp_init comes back clean. My problem is that I eventually get a timeout error "waiting for SYSCOMP & DBGACK". I have gotten as large as a 2MB file or so, and as small as 8k. Driving me nuts. > jtag init > halt target halted in ARM state due to debug-request, current mode: Supervisor cpsr: 0x20000013 pc: 0x4003957c MMU: enabled, D-Cache: enabled, I-Cache: enabled > dump_image mso1074z.bin 0x40000000 0x3FFFFFF timeout waiting for SYSCOMP & DBGACK, last DBG_STATUS: 4 I have been trying a variety of adapter speeds, delay and timing configurations, TDO clocking edge rise/fall, etc. I do not rely on a reset command between tries. I will power cycle both the dongle and the 1074Z. Is there a clue someone might have for me? Happy to share more detail about what I have tried. Thanks! 73 es God Bless, KK1L Ron <>< |
