Issues with T4240QDS with RCW BOOT_HO=1

quantran1234 — Thu, 15 Dec 2016 16:45:50 GMT

I recently opened a support issue for this and was assigned to Yiping, but for some reason my email responses started bouncing with an automated reply saying send it to tech.support@nxp.com, but I used that email, so I am not sure what the issue is. So I am asking here.

I have a board that we are trying to setup secure boot for, it is a T4240QDS system.

I am currently trying to get the CCS to work with the RCW image BOOT_HO=1, to verify CCS works and BOOT_HO works so I can use it to program the keys for secure boot.

The steps Yiping told me are as follow:
1. Please program boot hold off RCW to bank4 RCW address from bank0.

2. Please power down the target, modify SW6[1-4]=0100 to configure the target to boot from bank4, then power up the target board.

3. Please open CCS from Start->All Programs->Freescale CodeWarrior->CodeWarrior for PA 10.5.1->CodeWarrior Connection Server, then type the following commands.

% delete all

% config cc cwtap:<ip>

% ccs::config_chain t4240

% ccs::write_mem 0 0xfe0e00e4 4 0 0x00000001 Then you will see u-boot booting up on bank4.

I have done the steps 1 and 2 successfully, put the RCW with BOOT_HO=1 to bank4 RCW and set the SW6 switch to boot from the alternative bank. This seems to work because after booting from bank 4, the serial console doesn't output anything, so I assume it is holding until release.

I have some issues with the CCS step however, here are the messages I get from trying to use it

CodeWarrior Connection Server console display active (Tcl8.4.12 / Tk8.4.12)

HRESET occurred during transaction

(bin) 7 % ccs::write_mem 0 0xfe0e00e4 4 0 0x0000001

HRESET occurred during transaction

(bin) 7 %

How do I fix this error of "HRESET occurred during transaction"?

I find a same version T4240QDS board(Sys ID: 0x1e, Sys Ver: 0x14) as yours from our board farm, indeed the rcw 27_55_5_11 cannot work on this version board, please use the attached rcw 1_27_5_11.

Please boot the target board at bank0, program rcw to bank4, enter command "qixis_reset altbank"(this command can work at this version board), then open CCS console to type CCS commands. Please refer to the attached u-boot and CCS logs.

Have a great day,
Yiping
