      Sorry for disturbance, but I would need help to know if through the JTAG I can program an external flash connected to a microprocessor and in case which SEGGER SW/HW tool I have to use.
      The microprocessor is a “MCIMX6S5EVM10ACR” and through the EIM is connect to a “MT28EW01GABA1HPC-0SIT” Nor-Flash chip. Data bus is 16 bits (D0-15) and Address bus is 26 bits (A0-25). The signals CS0,OE,CE,RY,WE are connected. The microprocessor is provided with the JTAG interface.
      I need this because the Nor-flash chip usually is programmed before being mounted on the board, but now there is the need to rewrite the flash via JTAG to avoid having to disassemble and reassemble the chip from the board.
      Thanks.
    • Hello,

      Thank you for your inquiry.
      The Flash you are using is a CFI compatible Flash. In that case no extra
      Flash loader is needed. All you have to do is to init the memory
      controller of the MCIMX6 and configure J-Link to use that Flash as explained here:
      wiki.segger.com/CFI_Flash

      We recommend using a J-Link Plus or higher or a Flasher if you just need a programmer.

      Best regards,
      Nino
