topic Re: HRESET in CodeWarrior for QorIQ

HRESET

chrisyao — Thu, 09 Jul 2015 11:17:49 GMT

Hello,

We are trying to run the bare board example program of CodeWarrior on the T4240QDS.

HRESET is alaways on. Any clues on how to resolve this issue?

Any help will be appreciated.

Regards,

avt,chris

Please provide the fpga version displayed by uboot for your board.

Hi Adrian,

Thanks for your answer.

We worked on a bareboard of t4240qds, and just burn the fpga stp file: (file A)T4240QDS_Qixis_sys_cntrl_FPGA_140410\designer\QixMin_T4240QDS.stp .

There's no uboot running on this board. We want to program target board, but met something wrong with CodeWarrior TAP.

CW TAP can show the right MAC address when type in "findcc cwtaps -usb" on ccs console.

Q2: We tried to downgrade FPGA to this version, (file B)T4240QDS_2013_0509_1415.stp . Quote this link: CW won't debug T4240QDS: fails to reset target . And then got another messege: "IDCODE verify failed."

Both file A and file B IDCODE are the same string, 0653A1CF. IDCODE read from device : 1253A1CF .(we programmed file A before.)

This confused us, how to downgrade FPGA to file B.

thank you for your any suggetions.

For FPGA version 5 (T4240QDS_2013_0509_1415_V5), CW should works with no issues. I attached the image I used.

For FPGA version 6 (T4240QDS_2014_0522_1552_V6), CW will need a 2sec Reset delay (Go to Debug Configuration -> Edit -> Advanced -> Reset delay).

Dear Adrian,

The message: "IDCODE verify failed." shows again and again. We can't program these stp files. I don't known why and how ?

We got another errors when running CW debug:

"Error launching t4240qds-core00_RAM_T4240_Download

CCSProtocolPlugin : Failed to correctly configure the JTAG chain"

"Error launching t4240qds-core00_RAM_T4240_Download

CCSProtocolPlugin::Could not connect to the requested core #0."

Our ccs.cfg set to below lines:

“

delete all

config cc cwtap

config port 41475

ccs::config_chain t4240

ccs::reset_to_debug

ccs::all_run_mode

”

More infomations:

Three leds on our target board, label RESERT_RED, HRESET, SLEEP show some diff status,

When power on target board:

SLEEP blinking yellow, HRESER on red, RESET_RED off.

And more than 10 seconds later ,these leds always on till power off.

Did you used a flashpro programmer to program fpga files? If yes, this is not good, because a valid fpga image must be programmed on the board.

Dear Adrian,

Yes, we used the flashpro v4 to program fpga file on the board. The fpga file:T4240QDS_Qixis_sys_cntrl_FPGA_140410\designer\QixMin_T4240QDS.stp shows it was made on day 04/10/2014.

Dear Adrian,

Would you please help me to confirm whether the file is permanently encrypted?

Re: HRESET

addiyi — Tue, 21 Jul 2015 08:54:31 GMT

Could you try from CW, to add 2 sec Reset delay when connect to the board? Using some fpga version this is required by CW to connect to the board.

But, please make sure a valid fpga is programmed to the board.

Adrian

chrisyao — Fri, 24 Jul 2015 03:15:45 GMT

Dear Adrian,

We set the reset delay as 2000ms, but still can't connect target board, and the HRESET led still on.

The fpga is valid , when we found the diff stp files(mentioned above) worked not the same.

Would you please send us the whole fpga source files/projects, we want to compile the fpga step by step ourself.

Best wishes

chris

Unfortunately I don't have the source code for fpga, only the binary to be programmed into the board. You could open a service request and ask for source code.

As for me, I am curious about it as well.
