Boot issue

VisionFive（English Forum）
1

Use official images (second_bootloader, ddrint, opensbi/uboot) but the board could not boot, and there isn’t any log.

I could enter the recovery mode by long-pressing the power button,
and could also walk through the recovery process to reset the second_bootloader and ddr_init.

But the board still won’t boot in the normal mode, and no log could be captured.
(The baudrate has been checked, 115200 in normal mode and 9600 in recovery mode).

our boards were shipped only after the factory tested them without any problems.
Is it the first time power on the boards after receiving it ?It is recommended that the adapter use 5V/3A, the adapter has fast charging function better

1.make sure the connection is right
the normal mode should connect the uart (40pin),115200
the recovery mode should connect the debug pin
2. could you show me the log of recovery process

Thanks. I will provide the logs of recovery process later.

And there’re some updates for this issue:
If i comment out the following statements in the boot/bootmain.c: BootMain() function in the JH7100_secondBoot module,

//_SET_SYSCON_REG_register104_SCFG_io_padshare_sel(6);

the bootloader could boot in the normal mode. And ddrinit, opensbi as well as uboot could be loaded. But it seems that uboot fails to load image from Micro SDCARD.
This is the log captured after patching the bootloader:

NOTE: this is not the log of recovery process.

Yes, it’s the first time power on the boards after receiving it.

I actually use the charger for my phone, which is capable to output 5V/3A.

6

Oh, suddenly notice that i connected to the wrong pin for UART in normal mode.
I thought serial use the same pin for recovery mode and normal mode.

Will try again and report the latest status.

7

Can boot now with the original official image after i change the pin.
Thanks very much.
