LS1012A QSPI-Flashing Problem on Custom Board

[srikanthbomma]

Hi All,

We are trying to flash the default RCW to QSPI on our custome board based on "LS1012AXN7EKB". We have followed the referance schematics of "  LS1012A-FRDM".

H/W Settings (Hardcoded - RCW)
   CPU Part Number : LS1012AXN7EKB

   cfg_sysclk_sel (QSPI_A_CS0) -- Pull Down
   cfg_func_backup (QSPI_A_DATA1) -- Pull Down
   cfg_eng_use -- Pull-Up
   cfg_eng_use2 -- Pull-Up ( we are using External Clk)
   cfg_rcw_src -- Pull-Down

Target Initialization Script:
     USE_SAFE_RCW = True

we are getting the following error

/***************************************************************/
ERROR: Memory access failed.
//
Additional error details:
Failed to write memory at address 0x1ee00e4 on core CortexA53#0.
Core CortexA53#0 not found on the JTAG chain. Please verify that the Reset Configuration Word is correct, or enable RCW Override in the initialization file.
/***************************************************************/

H/W Settings (QSPI - RCW)

cfg_sysclk_sel (QSPI_A_CS0) -- Pull Down
cfg_func_backup (QSPI_A_DATA1) -- Pull Down
cfg_eng_use -- Pull-Up
cfg_eng_use2 -- Pull-Up ( we are using External Clk)
cfg_rcw_src -- Pull-Up (QSPI Selected)

Target Initialization Script:
   USE_SAFE_RCW = False

We have witten the RCW values to QSPI flash using External programmer.
RCW Values for your Ref

we have checked USE_SAFE_RCW = False and USE_SAFE_RCW = True in  "LS1012A_FRDM_init.py" .

Can you please check and let us know.

Thanks a lot.

Hello Srikanth Reddy,

Please configure the target board in hard-coded RCW mode.

Please configure cfg_rcw_src as 0 to configure the target board as hard-coded RCW, then use the procedure which I mentioned previously.

Thanks,

Yiping

[srikanthbomma]

Hello Yiping,

Thanks a lot for the reply and sorry for the late response.

The cfg_rcw_src is configured to 0. We are getting the same errors.

We are trying to check few signals in our hardware.

Is there any test we can do using the CWTAP to make sure the processor and the other peripheral are good.

Best Regards,

Srikanth.

[yipingwang]

Hello Srikanth,

Please check whether the CCS can connect to the target processor through CodeWarrior TAP. Please open ccs.exe in C:\Freescale\CW4NET_v2020.06\Common\CCS\bin\, then type the following commands.

(bin) 3 % delete all
(bin) 5 % source IDcode.tcl

Hello Yipingwang,

Thanks a lot for the reply. We have executed the procedure in ccs.exe which you have given.

This is the screenshot of the execution.

[srikanthbomma]

Hello Yiping,

Thanks a lot for the reply. We will check this soon as our board is having problem with the QSPI clk signal. We are trying to rectify that. Will let you know as soon as we check this.

Best Regards,

Srikanth Reddy.

We get the same questions as yours, can you tell me yours solutions.

 best wish ,thank you
