[microblaze-uclinux] Running uClinux with 8M memory?
I just modified mbvanilla_net_6_20_a to another board. The major
1. I modified the emc controller cuz I have 8MByte ZBT SRAM. I used
0xFF000000 - 0xFF7FFFFF for it.
2. I deleted the DDR controller and related DCMs cuz I don't have DDR on my
3. Since I haven't go the SDRAM working yet on my board, I have only 8MBytes
RAM to use.
4. I deleted the debug uart cuz I only have one uart port and I used it for
I have went through the EDK tool flow and written a simple uart test program
for it. It can run out of bram or I can init the BRAM with the xmd_stub and
I can use XMD to download and debug the software. Also, I can make the code
run out of ZBT SRAM.
I would like to try uClinux quickly on this platform, so I wonder if the
demo image will just work if I modified my SRAM memory to the original DDR
space,at least the starting address? Cuz looks like the current SRAM on
Memec board is not used by uClinux. Is 8M enough? Or in my case, I have to
modify the kernel source and recompile it to make it work on my platform?
Sounds like naive questions, but any feedback is appreciated.
