Добрый день!
Возникла необходимость в применении microblaze. Есть отладочная плата ML605 от Xilinx с Virtex 6 на борту.
Собрал проект, из-под ISE Project Navigator запустил XPS, создал с помощью визарда необходимую конфигурацию процессора. Сделал экспорт в SDK. Написал простенькую программку обмена сообщениями по I2C + моргание светодиодами.
Из-под SDK кнопкой Program FPGA загружаю прошивку в ПЛИС, жму Debug - всё прекрасно работает и стреляет.
Захотел имплементировать код elf файла в прошивку, чтобы при включении платы (ну или хотя бы просто при загрузке прошивки Virtex'a тем же самым Impact'ом) Microblaze начинал выполнять свою программу. И тут возникли проблемы. При загрузке прошивки в Virtex ничего не происходит, microblaze не стартует.
bit-файл для прошивки уже готовил двумя путями - 1. с помощью data2mem 2. подпихивал в XPS с последующей разводкой в ISE
Последующий дамп этих bit-файлов (с помощью data2mem) показал, что они одинаковы.
Шерстил форум, самое близкое, что нашёл - вот такую тему
http://electronix.ru/forum/index.php?showtopic=89879К сожалению, пока ничего сделать не получилось.
В файле линкера все блоки транслируются в BRAM, привожу кусок кода:
CODE
_STACK_SIZE = DEFINED(_STACK_SIZE) ? _STACK_SIZE : 0x400;
_HEAP_SIZE = DEFINED(_HEAP_SIZE) ? _HEAP_SIZE : 0x400;
/* Define Memories in the system */
MEMORY
{
ilmb_cntlr_dlmb_cntlr : ORIGIN = 0x00000050, LENGTH = 0x0003FFB0
xps_bram_if_cntlr_0 : ORIGIN = 0x81438000, LENGTH = 0x00002000
}
/* Specify the default entry point to the program */
ENTRY(_start)
/* Define the sections, and where they are mapped in memory */
SECTIONS
{
.vectors.reset 0x00000000 : {
*(.vectors.reset)
}
.vectors.sw_exception 0x00000008 : {
*(.vectors.sw_exception)
}
.vectors.interrupt 0x00000010 : {
*(.vectors.interrupt)
}
.vectors.hw_exception 0x00000020 : {
*(.vectors.hw_exception)
}
Bmm файл вроде тоже в порядке (но точно не уверен). Беру тот, что создаёт сам ISE.

В чём может быть проблема? Может не по тому адресу пишется программа? Или же кривой старт с ресет вектора? (вроде не менял, а вдруг надо).
Думаю, что решение довольно простое, но по форуму схожих проблем не нашёл (или просто плохо искал).
Заранее спасибо.
Не стартует Microblaze
