ls1028 boot

Hello

I encountered a problem while upgarding xspi image to NOR Flash
(I know , i should have started from sdcard first )
I followed the instuctions but due to some logistics problems
instead of uploading the (prebuild) xspi image via tftp i used XMODEM( it took me while )
So the load address was different from tftp load adrress
Standart uboot load address is 0xA0000000 - for TFTP
The xmodem address is 0x90000000
According to documentation(Table 1. System memory map)
both are valid( DRAM - GPP DRAM Region #1 (0-2 GB)) .

there were no errors while uploading image .

The standart burn command for NOR flash is (from docs):

4. Program the firmware to FlexSPI NOR flash.
=> sf probe 0:0
=> sf erase 0 +$filesize && sf write $load_addr 0 $filesize
5. Reset and boot the board from FlexSPI NOR flash. The system will automatically boot up TinyDistro (log in
using root/root) or LSDK distro (log in using root/root or user/user) available on the removable storage device.
=> qixis_reset

I tweaked the command to take xmodem load address (0x90000000) and filesize 54501351 (bytes)
sf probe 0:0
sf erase 0 +54501351 && sf write 0x90000000 0 54501351
here is snippet from my console :

=> sf probe 0:0
SF: Detected mt35xu02g with page size 256 Bytes, erase size 128 KiB, total 2 GiB
=> sf erase 0 +54501351 && sf write 0x90000000 0 54501351
SF: 1414660096 bytes @ 0x0 Erased: OK
device 0 offset 0x0, size 0x54501351

at this stage it hung and i never got to "qixis_reset" command

After that , the only was to see something in console
if i config deep switch to boot from emmc(i tried boot from sdcard )

here is console dump:

Resetting CPU ...

### ERROR ### Please RESET the board ###

So it seems like the problem heappans before uboot reloc someware in fip.bin :
I am not sure what heappened

My questions :

Is it recoverable ?
Is Jtag can reprogram NORFlash
Is it any way to recover?
Any help will be super appriciated

Thanks

You could use CodeWarrior for ARMv8 and CodeWarrior TAP to do recovery.

If you have purchased CodeWarrior license, please download and install the latest CodeWarrior for ARMv8 11.5.12 from NXP public Website.

Please sign in www.nxp.com, then download CW_ARMv8_v2020.06_b200629GA_Win_Offline.exe and CodeWarrior for ARMv8 v11.5.12 b221209 Windows Offline Update from My NXP Account->Software Licensing and Support->View accounts->NXP Software->CodeWarrior Networked Suite - Specialist Level->11.5.12 CodeWarrior for QorIQ LS Series ARMv8 ISA.

After install CW_ARMv8_v2020.06_b200629GA_Win_Offline.exe, please open CodeWarrior IDE and install service pack 11.5.12 from Help->Install New Software->Add->Archive

Then open CodeWarrior IDE, In Target Connections panel, please right click LS1028A_RDB to duplicate it to generate LS1028A_RDB(1), click "Flash Programmer" icon to connect to the target board to do flash programming, please refer to the attached screenshot target_connection.png.

Please refer to section "7.7 Using flash programmer from eclipse IDE" in

C:/Freescale/CW4NET_v2020.06/CW_ARMv8/ARMv8/Help/PDF/ARMv8_Targeting_Manual.pdf for details.

Are you bringing up your custom board?

If so, you need to modify DDR configuration section in ATF or u-boot source code.

You could refer to section "5.2.1.1 TF-A DDR Driver" in LSDK 21.08 user guide.

Thank you for your reply

Few quick questions :

Can CodeWarrior be installed on Linux mashine ?

Is it possible to work with third party flasher( Segger Jlink) as alternative just to write flash ?

Thanks for your help

It is possible to install CodeWarrior in the Linux machine, you could download CodeWarrior Linux installation files from the same path as I mentioned previously.

It is impossible for CodeWarrior to work with third party flasher.
