Sorry. Title is my mistake.
I can't changed title. : (
It is not clear from your statement regarding the size of the memory used.
Since PSoC5 has 256KB of Flash, it shouldn't cause any trouble in your case.
It will be helpful to debug if you can attach the modified project.
Hi dasg,I read your post this time. :oAs a matter of course, I thought it shouldn’t cause any trouble. However, as I mentioned before, it did not branch & exchange[BX] address to flash size larger than 64KB. It was happened the only USBFS Bootloader, as it turned out. Because it’s OK to I2C Bootloader project. =)Thank you for your reply.
