Hello community,

please can you let me know, how I may reflash the u-boot / RCW on a LS1012A RDB without a CW Tap?

As there is a Kinetis with JTAG firmware on the board I wonder if there is way to use this?

Many thanks,

Dieter

Re-flashing is possible using cmsis-dap, but make sure a valid RCW is available. Otherwise, only using CWTAP you can restore the board.

 

Also, note that cmsis-dap is very slow.

  Hi Adrian,

  many thanks for your support - that helped. Is there any further documentation how to configure a RCW / pinmux for LS1012A / ARMv8 devices and use them as default for own boards? Or in other words, what is "best practice" to make hardware adaptions - old fashioned way via dt adaptions or CW?

  Many thanks,

  Dieter

    Old fashion is ok, but using CW and QCVS (PBL tool and PinMux tool) it will be better. Take a look on www.nxp.com/qcvs for a short description of QCVS suite. Note that PBL and PinMux tools are free of charge.

  Hi Adrian,

  Also, note that cmsis-dap is very slow.

   

  Can you compare the speeds of the CMSIS-DAP to the CWTAP? Are there some additional things you can do with the CWTAP that you cannot do with the CMSIS-DAP?

   

  I need to make an argument to my manager in order to make the purchase.

   

  Thanks, Sabine

    cmsis-dap is several times low speed than cwtap (5 to 10 times slow). This and the fact that over cmsis-dap rcw override is not possible is the difference between cmsis-dap and cwtap.
