RE: Kess and ktag firmware
You can with cp2102 rewrite fw if nxp doesn't have crp3. If crp1 or crp2 you can rewrite the same fw with usb to ttl only.
CRP1 disables access to chip via the JTAG and allows partial flash update (excluding flash sector 0) using a limited set of the ISP commands. This mode is useful when CRP is required and flash field updates are needed but all sectors can not be erased. CRP2 disables access to chip via the JTAG and only allows full flash erase and update using a reduced set of the ISP commands. Running an application with level CRP3 selected fully disables any access to chip via the JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too. It is up to the user’s application to provide (if needed) flash update mechanism using IAP calls or a call to reinvoke the ISP command to enable flash update via UART0. |
