some problems when use usb codewarrior tap debug on my custom lx2080 board

[gec258]

my platfom:

CPU:LX2080CA

DDR: MT40A1G16

FLASH:MX25UW51245G , flash is blank.
sysclk 100M。
hardware link status :us

e usb link codewarrior,and code  warrior link my board with JTAG

when I refer to 3.2 Working with bareboard application in D:Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\Getting_Started_for_CW_ARMv8.pdf to debug my board, it always report "target connection error",

then I refer to  8.6 Board Recovery in CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\PDF\ARMv8_Targeting_Manual.pdf to modify Target Init File,

        USE_SAFE_RCW= True

        # Overridden RCW source
        TA.rcw.set_source(0x9F)
        # Overridden RCW registers will be added here
        TA.rcw.set_data({1: 0x586b6b18})
        TA.rcw.set_data({2: 0x24580058})
        TA.rcw.set_data({3: 0x00000000})
        TA.rcw.set_data({4: 0x00000000})
        TA.rcw.set_data({5: 0x00000000})
        TA.rcw.set_data({6: 0xc010000})
        TA.rcw.set_data({7: 0x00000000})
        TA.rcw.set_data({8: 0x00000000})
        TA.rcw.set_data({9: 0x30001a0})
        TA.rcw.set_data({10: 0x00002580})
        TA.rcw.set_data({11: 0x00000000})
        TA.rcw.set_data({12: 0x00000096})
        TA.rcw.set_data({13: 0x00000000})
        TA.rcw.apply()​

and refer to  https://community.nxp.com/t5/Layerscape-Knowledge-Base/LX2160ARDB-How-to-configure-a-new-flash-devic...    add new  flash config. change  Target Init File :

    fl.add_device({"alias": "xspi", "name": "MX25UW51245G", "address": 0x0, "ws_address": 0x18000000, "ws_size": 0x1FFFF, "geometry": "8x1", "controller": "FSPI"})

and my board hardware CFG_RCW_SRC[3:0] set to 4'b00xx.

when I click Flash Programer,It still report connection error.

and I tryed two Codewarrior Tap box, It shows same error.
Is there anything else I can check?

此问题已解决，是我们的硬件的有个jtag复位信号没接上。
还有一个原因是 TA.rcw.set_source()参考LX2160ARM手册的Hard-coded部分，这里只能填0x0/0x1/0x2。

If  it's a bare board, please set the RCW_SRC[3:0] to hard-code.

When you connect the CodeWarrior TAP, should confirm the board could complete the Power-On Reset Sequence.

LX2160A Reference Manual,

4.9.5 Power-On Reset Sequence Detailed Description, step 24, System Ready State.

4.9.6 Power-On Reset Sequence Timing

And CCS could connect the CWTAP correctly.

In the ccs, please run:

(bin) 7 % delete all

(bin) 8 % config cc cwtap:10.193.21.52//(it's your CWTAP ethernet IP)

(bin) 9 % show cc

(bin) 10 % ccs::config_chain {lx2160a dap}

(bin) 11 % display ::ccs::get_config_chain

(bin) 12 % ccs::reset_to_debug

Thanks

Thank you for your reply. we will check the power-on time sequence. my CWTAP box has been connected to the PC through USB.
On ccs, execute the show cc command according to the method you provided. After waiting for a while, the time out is indicated:

[June_Lu]

Could you ping the CWTAP?

What's your CWTAP version?

What's your CodeWarrior IDE version?

Please confirm update it to the CodeWarrior IDE version 11.5.12.

On the NXP website

My NXP Account->Software->Software Licensing and Support->View accounts->Product List->CodeWarrior for QorIQ LS Series ARMv8 ISA->

Please download update package

com.freescale.armv8.11.5.12.GA.Win.updatesite.221209.zip

Please open CodeWarrior from C:\Freescale\CW4NET_v2020.06\CW_ARMv8\fsl_eclipse.bat, and install the update package from Help->Install New Software->Add->Archive.

And then try the ccs command again.

You could reply the case in Chinese.

Thanks
