      I've done it example project is USBFS Bootloader for PSoC® 3 and PSoC 5(EP64299) in PSoC5. Also I worked to size up bootloader code. However, it doesn't work after making size up source.


      For example I enlarged the bootloader flash size to 74640 of 26144 bytes. In other words, flash sizes are gonna be larger than 64kb. Then I wrote bootloadable code to flash memory via USB but it doesn't work. I don't know why.


      Please let me know if you know the reason.

            Hi Lee,




            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. :o   
                   As 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.   

              Best regards,
