TDA4VH-Q1: uboot boot error

Hi,

I could not understand all the information in the attached zip file. Can you please share the exact error in U-Boot that you are seeing?

The phenomenon is that the program gets stuck as soon as it reaches U-Boot. The serial port of U-Boot does not print out any log. We connect to the debugger and obtain the data of DDR and registers. The content in the zip file is as follows:

1.80470000-80480000. Bin

2.80800000-80970000. Bin

These two are the dump data corresponding to the DDR address

3.reg.txt- Register values at the scene of the incident

4.u-boot- The elf file of U-boot, which contains a symbol table

5.uboot_early_abort_cr_122077956.md , uboot_early_abort_patch.md

These two are our own fixes to do_sync and the code for saving the added registers to memory

6.uboot_early_abort_dump_analysis.md

This is some analysis of the above-mentioned accident scene by ai

ddr_par.zipIt was generated using the excel tool SPRACU8B_jacinto7_DDRS_RegConfigTool, whose version number is 23rd,2023, 0.10.0 this is our ddr parameter，

the ddr_par.zip is our ddr parameter，It was generated using the excel tool SPRACU8B_jacinto7_DDRS_RegConfigTool, whose version number is 23rd,2023, 0.10.0 ，we just change the chip selects/ranks from 2 to 1，and multi DDRSS interleave memory size from 32GB to 16GB

Hi,

attachment is LPDDR4 schematic.

thanks

Hello,

If you are suspecting DDR at least some of the R5 SPL logs should be up and DDR could fail after that - Can you share the working and non working boot logs?
