altremote_update in Cyclon III

Hi all,

I just received from Altera Technical Support the solution of my problem and I want to share it (maybe it can be useful for someone else) :

From this SR database stated that you are using Quartus II v13.1.4. Is this correct? I checked from the remote update user guide, under Cyclone IV device, it mentioned that for the Quartus II software version 13.1 and onwards:

• Width of 29 or 32 when reading the boot address.

• Width of 24 or 32 when writing the boot address.

• For active serial devices using the 24-bit addressing, such as EPCS128 or EPCQ128, boot_address[23..2] corresponds to the upper 22 bits of the 24-bits boot address. boot_address[1..0] is read as 2'b0.

This should be applicable for Cyclone III too since the parameters for Cyclone IV and Cyclone III are the same. Thus when writing the application image boot address you need to set data_in[23..0]= 0x100000h and not 0x040000h.Write the 24bits and not the upper 22bits. Please try to do this and test the reconfiguration to the application image.
