CCSProtocolPlugin : Error writing memory [CCS last error: Scan timeout ]

kristinkrueger — Mon, 18 Aug 2014 13:37:21 GMT

Hello,

I followed the steps in this thread (CW won't debug T4240QDS: fails to reset target), downgraded the FPGA version and now CW gives me the above mentioned new error message. I already updated the drivers and firmware for the CW Tap. I'm working on the T4240QDS under Win7 and I try to run the example baremetal project.

Any help will be highly appreciated!

Kind regards,

Kristin

Could you please provide a ccs log (go to Debug Configuration -> Target Settings, Edit -> Advanced -> Advanced CCS settings and Enable logging )?

Also, did you use the default project generated by CW? Did you change init or mem file?

Hello Adrian, thank you for your fast reply!

I did not change any files and used the example project generated by CW. Where do I find the ccs log file?

Regards,

Kristin

Go to Console view, and select your current debug connection (something similar as in attached picture).

Here it is.

Please try a lower JTAG clock speed (now you have 4000 kHZ). If this not help, try to verify the switch settings to be according with the T4240QDS_eabi_README.txt.

From the other thread you input, it seems you are using a CGA_PLL2_RAT[34-39] 0b011000 which is not supported, see section 4.1.4 Core cluster to SYSCLK PLL ration in Technical Data of T4240QorIQ T Series T4240/T4160/T4080 24/16/8 Virt|Freescale

I verified the switch settings, they are according to the T4240QDS_eabi_README.txt. Setting the JTAG clock speed to 500/1000/2000 kHz did not solve the problem.

kristinkrueger — Tue, 19 Aug 2014 09:25:54 GMT

Thank you for your reply.

As I used the default switch settings, I can't explain the difference. So you propose to set the RCW manually?

Regards,

Kristin

You could use a default rcw and check if the error is still there. Then you should change the rcw and switches according with your setup.

Hello Kristin,

I suspect there is problem with your RCW, please try whether this problem could be solved by using CodeWarrior JTAG configuration file to override RCW on the target board, please refer to the section "Setting up a remote system to use a JTAG configuration file" in CW_PA_v10.4.0\PA\Help\PDF\Targeting_PA_Processors.pdf.

In addition, please note to check the initialization file after configure JTAG configuration file.

For any result, please kindly let us know.

Have a great day,
Yiping

Hello Yiping,

thank you for your help.

I set the RCW manually and I don't get any errors anymore, but the console output is still missing. The serial connection is up and running, I can read the system information etc. after bootup, but when I run the example code, there is no output generated. When I try to debug, it does not stop automatically, and if it do this by hand, it stops somewhere in dissassembled code (screenshot attached). What prevents the output?

Additionally, what should I check in the initialization file?

Regards,

Kristin

This happens also using the stationary project?

Re: CCSProtocolPlugin : Error writing memory [CCS last error: Scan timeout ]

kristinkrueger — Mon, 25 Aug 2014 13:41:33 GMT

Yes.

Re: Re: CCSProtocolPlugin : Error writing memory [CCS last error: Scan timeout ]

addiyi — Mon, 25 Aug 2014 13:59:58 GMT

Check the followings:

- rcw (use the one attached)

- init file (use the one attached)

- switch settings, should be like in readme file (T4240QDS_aeabi_README.txt)

- also check the serial console speed to be 115200

- check the serial cable and the serial port on board.

Which flash configuration file should I use to program the RCW with CW flash programmer?

Re: CCSProtocolPlugin : Error writing memory [CCS last error: Scan timeout ]

addiyi — Mon, 25 Aug 2014 14:57:54 GMT

For programming rcw binary to NOR, from Target Task, just import PA\bin\plugins\support\TargetTask\Flash_Programmer\QorIQ_T4\T4240QDS_NOR_FLASH, then create Add Program Action, select Erase sectors before program, set the Address Offset to 0xE8000000 and browse for the rcw binary.

Hello Kristin,

It looks that there is problem with DDR controller initialization.

Please try whether it would be better to use SRAM(to replace DDR) initialization file.

Have a great day,

when I try to program the flash the way you mentioned I get the following output and error:

Hello Kristin Krueger,

As discussed previously, it seems there is problem with DDR controller initialization, which causes the flash algorithm cannot be run successfully.

Would you please try to use the SRAM initialization file instead to do flash programming?

Please refer to the attachment in the following post.

Have a great day,
