BeMicro SDK - how to access SD card

I have given up on using the uSD Card slot... I have managed to get the web server running from EPCS memory, the guide is as follows:-

1) update the simple web server as in the first post, source code and bsp, make sure it runs

2) go to the bsp editor, software packages….. change the following:-

ro_zipfs_base: to 0xa003800 (which is the base address of ecps memory)

and make sure :-

ro_zipfs_offset: is 0x100000 (offset to where we will program the flash pages)

(reference attachment)

3) generate the bsp

4) the code (ro_zipfs.c) for extracting web pages from memory mapped parallel flash will not work with epcs serial flash, this has to be modified:-

reference attached zip file,altera_ro_zipfs.c.zip,which contains the original Altera file and a corrected version of DrinkFish file

Replace the original for the corrected one, reference this post for additional details http://www.alteraforum.com/forum/showthread.php?p=132498#post132498

The following commands are run using the noisII command shell

5) Convert the webpages (ro_zipfs.zip) to an S record file with an offset of 0x100000, use the following command

bin2flash --location=0x100000 --input=ro_zipfs.zip --output=ro_zipfs.flash

6) To program the web-server pages to the serial epcs memory use the following command

nios2-flash-programmer --epcs --base=0xa003800 ro_zipfs.flash

(note:- it will be programmed at the offset specified in 5, in this case in the middle of epcs memory and does not affect the fpga configuration section)Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Resetting and pausing target processor: OK

Checksummed/read 26kB in 0.6s

Erased 64kB in 0.6s (106.6kB/s)

Programmed 39KB +25KB in 0.6s (106.6KB/s)

Did not attempt to verify device contents

Leaving target processor paused

6a) Additional Info - You can read the whole contents from the epcs memory by running the following command:-

nios2-flash-programmer --epcs --base=0xa003800 --read=epcs_memory_contents.srec --read-bytes=0,0x200000Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Resetting and pausing target processor: OK

Read 2048KB in 49.7s (41.2KB/s)

Writing EPCS contents to current.srec

Leaving target processor paused

6b) Additional Info - To visually see the contents of this file (i.e. in a binary format) can be done by using the s record import function in “hexworksshop”

(remember to re name the file epcs_memory_contents.srec to epcs_memory_contents.srec .mot i.e. mot extension)

[/INDENT]7) First Clean and Compile BSP, then Clean and Compile the application

That’s it...
