    Bootloader and flash RWW

    jhu_3414236

      The bootloader SDK AN213924 says:

       

      PSoC 6 MCU flash has a read-while-write (RWW) capability across 256-KB regions. That is, the bootloader code

      may execute in one flash region while updating flash in another region.

       

      My application is large and I cannot reserve 256KB for the bootloader.  I modified the sample bootloader memory config to this:

          flash_app0_core0  (rx)  : ORIGIN = 0x10000000, LENGTH = 0x10000

          flash_app0_core1  (rx)  : ORIGIN = 0x10010000, LENGTH = 0x10000

          flash_app1_core0  (rx)  : ORIGIN = 0x10030000, LENGTH = 0x20000

          flash_app1_core1  (rx)  : ORIGIN = 0x10050000, LENGTH = 0x10000

       

      Bootloader and app1 are both in the same 256KB region and everything still seems to work after I perform the app loading.  Am I allowed to put app1 code in the same 256KB region as bootloader?
