remote update with stratix GX

Hi all, 

 

I'm trying to do remote update using Stratix GX and EPC16 (yes parallel, not serial...) as a memory device. I'm also using Serial II protocol to send the data. 

 

My design (page 0) includes Altera's altremote_update megafunction and a flash interface to read from and write to the flash in the EPC16. The flash interface is a design I have created according to Numonyx M28W160C datasheet. After every word I'm writing to the EPC16's flash I'm reading it to verify. 

The data sent (page 1) is a RBF file that I have created using Quartus II file convertor. 

The configuration mode is PS 1 bit. 

 

When I'm sending the data I'm promoting the addresses myself and updating the options bit at the end of each page I'm writing (currently only 1). 

 

The problem is that when I'm sending the command to the altremote_update megafunction to reconfig page 1, page 1 is not reconfigured into the Stratix GX. 

 

At the moment it looks like the writing and reading are OK but when I'm sending the command to the altremote_update megafunction to reconfig page 1, page 1 is not reconfigured into the Stratix GX.  

 

I have done another experiment where I have created a POF containing both page 0 and page 1 and burned it to the EPC16. I turned on the power and sent the command to reconfigured page 1, and it is, indeed, being reconfigured. 

 

 

Can anyone, please, tell me what might be my problem?  

 

Thanks, 

Alon Goren
