Hello,
I am using cyclone V with S25FL064 flash. I generate a sof with rsu for both factory image and user image, and coverted all of them into .flash. The address of two apps is just after the sof. Address arrangement(memory map): Factory: 0x000000 sof 0x17xxxx factory image User: 0x200000 sof 0x37xxxx User image All of the .flash are burned into S25FL064 with nios2-flash-programmer. After resetting, the factory image boots well and starts to reconfig to user image, but it fails to reconfig to the user image and reboots again. From the scope, I capture a negative pulse on nStatus, at the same time conf_done also goes low (keep low around 600ms, then goes high. I think it because the reboot succeeds), nothing changes on nConfig. After reboot, the rsu status is read as 0x04 which indicates nStatus fail. Could anyone help? I do very appreciate for any proposal. Best Regards hdaiLink Copied
