Пытаюсь собрать системку с MicroBlaze на Virtex-4 XC4VLX80. XPS собирает платформу нормально. Использую только BRAM.

Затем, при попытке собрать прошивку вот так ругается:

ERROR:Data2MEM:47 - Not all BitLanes in ADDRESS_SPACE 'microblaze_0.bram_block_0_combined' have BMM location constraints.
    Some data for this ADDRESS_SPACE may be lost during BIT file
    replacement. Verify that the BMM file has location constraints
    for all BitLanes.

Я не могу понять, как собственно должен выглядеть этот файл :laughing: (он его сгенерил автоматически).

Вот его содержание:

Существуют два BMM файла.

Первый формируется при синтезе.

Второй - после трассировки.

Второй файл выглядит так:

    ADDRESS_SPACE bram_block_0_combined RAMB16 [0xFFFF0000:0xFFFFFFFF]
        BUS_BLOCK
            ppc/bram_block_0/bram_block_0/ramb16_0 [63:62] PLACED = X3Y8;

            ppc/bram_block_0/bram_block_0/ramb16_31 [1:0] PLACED = X4Y1;
        END_BUS_BLOCK;
    END_ADDRESS_SPACE;

Обратите внимание на атрибут PLACED - он показывает где расположен блок памяти.
