s32r45 unable to boot from eMMC

[sinetech]

Our PCB is unable to boot from eMMC, while SD card boot works fine.

After burning the image named fsl-image-auto-s32r45evb.sdcard to eMMC using S32FlashTool_v2.1.4 via serial, and setting the boot selection to eMMC boot, nothing is output on serial port 0.

Please let the expert take a look and see where the problem lies.

Hello,

I was speaking with Radar team and you have to have correct:

1. boot cfg

Please confirm that you are using correct configuration 001b.

And have you SW at correct offset location loaded:

Best regards,

When using 4 data lines in the eMMC circuit, the eMMC signal lines adopt 1.8V.

A new discovery: after 8 reboot attempts, the BootROM enter serial boot mode.

hello, Peter
The file I flashed is the officially downloaded file fsl-image-auto-s32r45evb.sdcard. Is the console output defaulting to serial port 0 with a baud rate of 115200?
Best regards

hello,

Please confirm that the boot configuration setting '001' means 'reserved'. I have tried the boot configuration 011 and 001.

IVT correct offset location loaded, the following image shows the data read from the eMMC.
