    JTAG - partial programming

      HI all,

      I have a question regarding programming features of the CY8C38xx devices.

      In our application we would like to program the CY8C38xx device mainly from JTAG, but using I2C bootloader we would also like to program Cypress device via I2C, easyiest way to fix bugs :) but I am concern because part of the internal flash it will be used to store vital parameters (calibration values, settings, etc...)

      ARM based MCU's have this fabulous features that users can program only the specific part of the internal flash (single banks). I am wonder how is this done in Cypress?

      If anyone can point me any document describing JTAG functionality or give me an advice on how to do this partial programming.


      Thanks a lot. Sash
