Загрузка образа ОС
Загрузка осуществляется с помощью утилит mjtagserver и mdb, данные утилиты доступны на сайте ЭЛВИС.
Запустить mjtagserver на инструментальной системе:
sudo ./mjtagsrv Listening on @/tmp/mdb.sock alwaysOn=1
Далее с помощью утилиты mdb и скрипта для нее произвести инициализацию и запуск платы. В скрипте для mdb добавит строки запуска к файлам ipl и загрузки образа системы:
loadelf <path-to-image>/ipl-mct06em-ram loadbin <path-to-image>/mct06em.bin 0x80018000
Вывод запуска скрипта для mdb:
reset reset sleep 1 core risc set 0xb82f4004 0xffffffff # CLK_EN. enable all clocks set 0xb82f4000 0x00009099 set 0x182f300C 0x83 set 0x182f3000 0x43 set 0x182f300C 0x3 set 0xb82f1000 0x00b000f8 # CScon0 for SDRAM , virtual address 0x80000000 set 0xb82f1004 0x009f08f8 # CScon1 for SRAM , virtual address 0x88000000 set 0xb82f100c 0x000F0000 # CScon3 set 0xb82f1014 0x01ad0030 # SDRCON for SDRAM set 0xb82f1018 0x00f50222 # SDRTMR for SDRAM set 0x182f101c 0x40 # SDRCSR init SDRAM set 0xb82f101c 0x1 # SDRCSR init SDRAM loadelf <path-to-image>/ipl-mct06em-ram loadbin <path-to-image>/mct06em.bin 0x80018000 run
В результате выполнения приведенных выше команд должен запуститься образ ЗОСРВ, выведены сообщения о ходе загрузки и запущен командный интерпретатор. Пример вывода:
