There is a problem with the flash curing.

Error (209025): Can't recognize silicon ID for device 1. A device's silicon ID is different from its JTAG ID. Verify that all cables are securely connected, select a different device, or check the power on the target system. Make sure the device pins are connected and configured correctly.
Error (209012): Operation failed

The information I currently have is that the SOF file can be downloaded normally, but when I attempted to perform the firmware flash operation, an error (209025) occurred at the download progress of 80%, indicating that the silicon ID of device 1 could not be recognized. I don't understand why this happened. I referred to other successful circuit diagrams and used the standard AS mode flash serial mode, but still failed. Later, I re-soldered multiple times, but the problem remained unsolved. Eventually, I suspected that there was a problem with the flash memory. I replaced the EPCS4, but still couldn't solve it. I don't know if this is related to the issue of drawing equal-length lines or if there are other problems. Could you please tell me exactly what the problem is?
