Unable to boot P2041rbd

[ayhmi]

Hello,

I am using P2041RDB. While i was trying to change the boot firmware, i erased the flash and wrote a wrong image to the NOR flash. Now i can't access to the cores with debug probes. I am using two different debug probes one of which is USB Tap. I realized that i corrupted the RCW settings according to the discussion board is unable to boot. I tried the instructions in Section "Setting a Remote System to Use a JTAG Configuration File" and "A.2 Using JTAG Configuration File to Override RCW" in document "Targeting_PA_Processors.pdf" but now JTAG fails with message "Failed To configure the JTAG chain". I tried the instructions in i am getting "Failed to configure the JTAG chain" when trying to test RCW Override functionality of ... but i couldn't override RCW. Please help me to re configure my board to its initial state.

Thanks in advance,

Omer

Hello Omer Eskizara,

Please refer to the attached configuration.

If your problem remains, please attach the CCS log to us.

Please enable CCS log from "Run->Debug Configurations -><project>-core0_RAM_<processor>-Connect(Download)->Edit...->Advanced->Advanced CCS setting->Enable logging", and connect to the target from "Run->Debug Configurations-><project>-core0_RAM_<processor>-Connect(Download)->Debug”, the CCS log will be displayed in the console panel in CodeWarrior IDE.

  If the CCS log in the console is truncated, please enlarge the console buffer from Window->Preferences->Run/Debug->Console->uncheck "Limit console output".

  (Please open the console panel from Window->Show View->Console, and if nothing displayed, please choose the correct session on the right top icon in the panel.)

Have a great day,
Yiping

Hello Omer Eskizara,

Which version p2041rdb do you use? Please make sure you use the appropriate CW jtag configuration file.

Please try whether hard-coded RCW would be helpful.

For P2041RDB-PB set SW1[5..1]:RCW_SRC[0:4] to a hard-coded RCW option 0b1_0010.

Have a great day,
Yiping

Hello Yiping Wang,

I am using P2041RDB-PC. In jtag_chains folder there are configuration files "P2041RDB_RCW_1000-533-1066.txt" and "P2041RDB_RCW_1000-750-1333.txt" i tried both but none of them working. I tried changing RCW_SRC[0:4] to a hard-coded RCW option 0b1_0010 which yields the same ccs log.

Thanks,

Omer

[yipingwang]

Hello Omer Eskizara,

For P2020RDB-PC, please use the attached JTAG configuration file, it's better to use CW 10.4.

If you use hard coded RCW, please don't use CW JTAG configuration file, please create a new bared board project and connect to the target.

Have a great day,
Yiping

I've encountered the same problem with P2020RDB-PCA board. Can you send me a p2020 jtag file that match the P2020RDB-PCA board. I'm using Code Warrior 10.5, but there is no related jtag file with p2020.

Thank you so much if you could help me !

Hello Yiping Wang,

I also tried with CodeWarrior 10.4.0. Problem still exists. I couldn't manage to show CCS log on console but i attached the diagnostic information.

Thanks,

Omer

[yipingwang]

Hello Omer Eskizara,

You didn't specify the correct connection type, please choose "USB TAP" from Run->Debug Configurations-><project>-core0_RAM_<processor>-Connect(Download)->Edit->Connection type, because you are using old product USB TAP rather than CodeWarrior TAP.

USB TAP is also the probably cause, do you have other target to verify whether no problem with this TAP

Thanks,

Yiping

Hello,

I couldn't manage to override RCW settins with USB TAP. So I used another JTAG with a different program. I could manage to upload u-boot and RCW settings. My hardware is working atm. I resolved my problem with this new device. Thanks for your help.

Hello,

I ran some tests and I succeeded to use the board after RCW deletion in two ways

1. using a hardcoded RCW
2. using RCW overwrite

** my setup **

P2041RDB-PB, rev1 CPU

CW 10.4.0, build 140709

USB TAP

** details for board recovery **

1. using a hardcoded RCW

Initially switches set to boot from NOR (SW1[5:1]=01101)

boot the board with serial cable connected so we can see u-boot prompt

make a simple bareboard stationary project to enter debug on the board (RAM target)

use Flash Programmer to erase the first sector -> we no longer have RCW, if we try now to enter debug it fails

power off, set switches to 10010, power on -> we see the u-boot prompt again.

(the rest of the switches are exactly like described in the readme file from the generated project)

2. using RCW overwrite

set the switches to 01101 to get the RCW from NOR flash, from where we deleted it. (it doesn't boot now)

make a new bareboard stationary project, but this time with a SRAM target.

build the generated project

edit your target type to put your jtag chain file (I tested with both of them and it worked)

make sure you select your SRAM init files for the Initialization and Memory tabs.

(maybe the memory file is not really mandatory, but I used it anyway)

after this you can enter debug with this project and then use Flash Programmer to write again the RCW.

regards,

Catalin

Hello Yiping Wang,

RCW Source setting is 0b0_1101. I tried the attached configuration file and debug fails in the same step as following:

ccs_reset_to_debug

  serverh = 0

  cc = 0

  ccs_reset_to_debug; ccs_error = 39

  Error message: p2040: Core not responding

I was using Code Warrior 10.2.1. I am now downloading 10.4. I will post the results after i try with the new version.

Thanks,

Omer
