The DDR configuration is modified when the Linux of the IMX8QXP is started. When the compiled flash.bin file is burnt using UUU, the following error is reported, and no information is displayed on the serial port.
[HID(R):LIBUSB_ERROR_TIMEOUT ] SDPS: boot -f imx-boot-imx8qxpmek-sd.bin-flash
In addition, another compiled flash.bin file is available, as shown in the following figure.
The operations are performed according to the 《Bootloader Customization of the i.MX8X Board Development Board 4.14.98_ga》. Only the following modifications are made: The DDR configuration file of the SCFW and the DDR size in the U-boot. Does anyone know the cause? Am I missing something?
Thank you very much.
i follow the guide and compile the flash.bin success, but it seems doesn't work.
It even do not have just one line log from the serial.
when i excute "uuu.exe -v -b spl imx-boot-imx8qxpmek-sd.bin-flash", it shows
Since it fails at the first command, most likely the issue is the DDR configuration. Please follow the steps from the DDR Stress Test documentation and used the tool to check if the DDR config files are working.
