Fail to connect T1023 custom board using CW TAP

[abineshselvaraj]

We are using a custom board which is based on T1023-RDB design with some memory configuration changes. The system is booting u-boot from SPI NOR (S25FL256S - 32MB). I want to flash the u-boot bin in the NOR flash.

I'm using the following tools,

CodeWarrior IDE for Power architecture v10.5.1 windows

CodeWarrior  TAP (Over USB)

Probe Tip for Power-Architecture CodeWarrior (CWH-CTP-COP-YE)

I have created a code-warrior executable project and imported the existing flash programmer XML file of T1023RDB-SPI-FLASH (64MB).The flash programmer task has been updated with program/verify action (flash offset as 0). When the project is executed, following error message is shown,

"FAILED TO CONFIGURE JTAG CHAINS". On enabling the JTAG diagnostics, following message is shown in console,

"ERROR MEASURING IR SCAN LENGTH".

Kindly suggest the reason and possible solution for this issue,

Thanks & Regards,

S.Abinesh.

Seems to be a jtag issue. Please run in ccs console the followings commands and provide the output:

(bin) 50 % source IDcode.tcl

(bin) 51 % delete all
(bin) 52 % config cc cwtap
(bin) 53 % ccs::config_chain testcore
(bin) 54 % jtag::lock
(bin) 55 % jtag::reset_tap 1
(bin) 56 % jtag::reset_tap 1

Hi Adrian,

Sorry for the late reply. With 64bit OS, the TAP MAC-Address is read properly. Please find the ccs log for  JTAG scan test,

Please provide your suggestions.

As I suspected, there is a problem with your jtag interface. Please check jtag interface. You can take a look on the RDB board or any other nxp board, to see the implementation.

Adrian

[abineshselvaraj]

I will check and update you on this.

Thanks,

S.Abinesh.

When jtag works fine and running IDcode.tcl, you should see the IDCODE of the SoC, something like below

TDO -----
|
* Device 0 IDCODE: 5BA00477 Device: ARM DAP rev 5.x
(TAP Linked with Device: NXP LS2085A rev 1.x IDCODE: 0A01E01D)

I didn't see the device-ID of T1023 SoC, when the IDcode.tcl is running. But I'm sure that, the JTAG interface is correct. I have verified this with our HW Team. Is there any specific initialization files to be loaded in the T1023 board from CCS IDE for JTAG connection?

Thanks,

S.Abinesh.

[addiyi]

IDcode.tcl it is basic jtag test that is trying to read SoC IDcode. If the IDcode is not returned means the jtag is not working fine. Also, using jtag scan io command from ccs, wil test the jtag. Same on this, the returned values are not correct.

Adrian

[abineshselvaraj]

The JTAG that we are using now is a new one. Did you mean that, there is a internal problem in JTAG hardware or there is an issue in  probe-tip from JTAG to T1023 board.

Thanks,

S.Abinesh.

I refer only to jtag interface on the board. Once IDcode will be displayed by ccs, you will be able to use CodeWarrior.

Hi Adrian,

When the IDcode.tcl is sourced, I'm getting an error "No TAPs found connected through USB". Also, in the "findcc cwtaps" command, the jtag firmware version is not getting displayed. But, in the device manager, under ports -> codewarrior console port is visible. The green led in TAP is blinking.

Do you use CodeWarrior Tap or the old USTAP? Try in ccs console findcc utaps as well, to see if you get some output.

Adrian

[abineshselvaraj]

I'm using Codewarrior TAP (has both USB and Ethernet interface). The console is not displaying anything with "findcc utaps" also.

Thanks,

S.Abinesh.

Check in device manager to have Freescale Probes > CodeWarrior TAP visible. If, this is not visible try to reinstall the driver running as admin setup.bat from \PA\ccs\drivers\usb\

Adrian

[abineshselvaraj]

The device manager has the Freescale Probes > Codewarrior TAP visible.

Thanks,

S.Abinesh.

This is strange. Try using the ip address when configure the connection: config cc cwtap:<ip_addr> or when runnig IDcode.tcl select the first option 1, then specify the ip.

Hi Adrian,

Currently, I'm using PC with Win7-32bit OS, CCSv10.5 installed. When I try to read JTAG firmware version from CCSv10.2 exe in Win7-64bit PC, the mac-address and bootloader version of JTAG is displayed.

Thanks,

S.Abinesh.

Please provide a verbose ccs log (enter in ccs console: log v) when you are trying to connect to board.

Adrian

[abineshselvaraj]

Thanks for the reply. I will provide  the ccs log by tomorrow early.

[abineshselvaraj]

Hi,

Please find the ccs log below,

To get the ccs log, you have to open ccs console (ccs.exe) from \PA\ccs\bin\ and in console enter "log v" command. then try to connect to the board.

One question: your board is booting correctly the uboot from spi?
