Hello, My system has size limit. I can only have ICACHE,
without DCACHE, and there will be NO LMB BRAM at address zero. Instead, FLASH
will be at address zero and a bootloader will run from flash and copy linux
image to SDRAM for execution. I am not sure if Petalinux could be configured in
such a system? I’ve tried to build a similar system
withour DCACHE, but with LMB BRAM at address zero, it does not boot up and
there is no message showing on UART console. System brief: Microblaze with ICACHE enable, DCACHE
disable MCH_OPB_SDRAM: one XCL channel, OPB_IPIF
enabled FLASH: (set to address 0 for Microblaze) UART No LMB BRAM (where IRQ and RESET vector
resided at address zero) Thanks -Kevin |
