RE: RZ/A1 RSK XIP QSPI Reprogramming Apps Partition

The issue might be that with dual spi flash, the address you pass to erase the chip is half the address you access it with (1800_0000). The reason is that in spi mode, each api flash address holds 2 bytes. So then in xip mode, even asdresses are in api flash 0, and odd addresses are in spi flash 1.

This would mean xip addresses 1A00_0000 and 1A00_0001 are really spi address 0100_0000 (2 byte read...because each api address holds 2 bytes, not just 1...so xip address increment twice as fast as spi addresses.
