Unable to use EPCS device

Altera_Forum · ‎09-17-2011

Hello,

I am getting some experience with Altera FPGA's and ran into the following

issue.

I want to program FPGA configuration data (NIOS II processor) and the program into the EPCS memory on my DEx-board.

I want to do this with the NIOS II Flash Programmer.

When running this program I got the following error:

EPCS signature is 0x16

EPCS identifier is 0xC22017

No EPCS layout data - looking for section [EPCS-C22017]

Unable to use EPCS device.

When I add the next lines to the "nios2-flash-override.txt"-file I got the error : Syntax error in override file (line 2) when reading the file.

 
 *# EPCS1N (lead-free)
sector_size = 32768
sector_count = 4
 *# EPCS4N (lead-free)
sector_size = 65536
sector_count = 8
 *# EPCS16N (lead-free)
sector_size = 65536
sector_count = 32
 *# EPCS64N (lead-free)
sector_size = 65536
sector_count = 128

Can anybody help me with the newby question?

Thank you and best regards,

Wamor

Hello,

For some reason I have mixed up some numbers.

After adding the following line everything works ok:

 
C22017] *# EPCS64N (lead-free)
sector_size = 65536
sector_count = 128

Best regards,

Wamor
