Cannot download ELF; I-Side Memory Access Check Failed

Hello, 
 

I have a Microblaze project on the ML402 (Virtex-4) 
board under EDK 11.2, and I am unable to download a specific ELF I 
have created to the board. Other software applications (both EDK 
generated and programmed by myself) can be successfully downloaded and 
run as part of this EDK project, but not the one I am currently work 
on. 

 

The following is the output I receive: 
==== 
XMD% dow udp_temac_test/executable.elf 
System Reset .... DONE 
Downloading Program -- udp_temac_test/executable.elf 
section, .vectors.reset: 0x00000000-0x00000003

ERROR: Failed to download ELF file. 

I-Side Memory Access Check Failed 
Section, 0x00000050-0x00012c3b Not Accessible from Processor I-Side 
Interface 

==== 

 

Had anyone had this issue before? Anyone have any idea what might be 
causing it / how to solve it? 

 

Thanks in advance, 

 

Sean.

Hi,

 

I don't think your BRAM is large enough to cover the address 0x00000050-0x00012c3b. XMD gets the address mapping information from XMP project and won't allow you to download a code to an address that has no memory mapped.

 

To solve the issue, define a linker script and assign the code to an appropriate memory.

Hi,

 

Check your linker script first. When programming the FPGA using SDK, make sure bootloop.elf is initialized to BRAM.

And then continue debugging.
