Здравствуйте.
Имеется плата TQ6410 (s3c6410) и клон jlink v7 с последней прошивкой.
Первое чем пугают
SEGGER J-Link Commander V4.20h ('?' for help)
Compiled Oct 19 2010 14:02:03
DLL version V4.20h, compiled Oct 19 2010 14:01:59
Firmware: J-Link ARM V7 compiled Sep 6 2010 10:43:31

WARNING: At least one of the connected devices is not JTAG compliant (IEEE Std 1149.1, 7.1.1.d, IR-cells). (NumDevices = 5, NumBitsSet = 2)
WARNING: CPU core not found.
No devices found on JTAG chain. Trying to find device on SWD.
WARNING: CPU core not found.
****** Error: Parity error (Data = 0xFFFFFFFF, ReceivedParity = 1)

Did not find any core.
Info: TotalIRLen = 9, IRPrint = 0x0011
*** J-Link V4.20h J-Link V4.20h Warning ***
You are using a J-Link which does not have intelligence for the
selected CPU core (ARM11).
Intelligence enables J-Link to generate sequences for the CPU core.
Without this feature, all sequences are generated by the PC.
Intelligence allows higher target interface speeds and significantly
enhances both speed and stability of the communication with the
target CPU.
You can use this J-Link with your target CPU, but we recommend
using a newer model of J-Link / J-Trace.
*** J-Link V4.20h J-Link V4.20h Warning ***

Есть уменьшить частоту до 1Кhz то вроде всё хорошо.

Далее хочу остановить и продолжить выполнение программы.
Запускаю плату, торможу в eboot, жму несколько раз R -- конфиг перечитывает - ок.
запускаю opencd, подключаюсь

Вроде остановилась, в консоле на R уже не реагирует. Пытаюсь запустить продолжение

Отработала, но консоль не ожила.

(И вдруг pc уже в нулях. Почему?)
Почему не сработала resume?
Спасибо.
