T4240RBB : Unable to connect CodeWarrior JTAG

Arathi — Thu, 24 Aug 2023 10:08:53 GMT

Hi NXP Support Team,

I am having T4240RDB board and I have some flashed images on the Flash memory.
Now I have made new RCW configuration and need to load it using Code Warrior JTAG.

I have made the board JP1 Jumper setting to JTAG mode and have verified that board is not booting UP. Then I have connected CWTAP JTAG to the CPLD JTAG port. On CodeWarrior tool DDR validation part,
I am unable to get the target connection as connected.

Is there any other switch settings to be taken care?
Please do help me resolve this.

Thanks and Regards,
Arathi

Please configure the switch setting as the following.

SW1 : 0x3 = 1100 SW2 : 0xF = 1111 SW3 : 0xF = 1111 SW4 : 0xF = 1111

Note: ON side is 0, the other side is 1.

Please open CCS console from C:\Freescale\CW_PA_v10.5.1\PA\ccs\bin\ccs.exe, then type the following commands and send the result to me to do more investigation.

(bin) 175 % delete all

(bin) 176 % config cc cwtap

(bin) 177 % show cc

(bin) 178 % ccs::config_chain t4amp

(bin) 179 % ccs::reset_to_debug

Hello, Power Supply: Ensure the board is powered on. JP1 Jumper: Confirm once again that the JP1 jumper is correctly set to JTAG mode. If this jumper is not set correctly, the board may still attempt to boot from Flash or another source. CWTAP Connection: Double-check the connection of your CodeWarrior TAP to the board's JTAG interface. Ensure that the connector is oriented correctly and securely attached. CodeWarrior Configuration: Ensure that CodeWarrior is set up for the correct target (in this case, the T4240) and that you've chosen the right connection settings.

Hi @yipingwang,

The switch is configured as follows:
SW1 : 0x3 = 1100 SW2 : 0xF = 1111 SW3 : 0xF = 1111 SW4 : 0xF = 1111

But I am unable to open CCS console from C:\Freescale\CW_PA_v10.5.1\PA\ccs\bin\ccs.exe

please do let me know how can I proceed further.

Thanks & Regards,
Arathi

Just double click file C:\Freescale\CW_PA_v10.5.1\PA\ccs\bin\ccs.exe, CodeWarrior Connection Sever icon will pop up in your Windows task bar, then double click the CCS icon in your Windows task bar, the CCS console will be open and type the previous commands which I suggested.

If you still cannot open CCS, probably there is problem with your CodeWarrior installation, please reinstall it.
