I investigated this boot issue. U-Boot 2020.04 works, but 2020.07 does not.

I run a git bisect and found that the guilty commit was:

commit c738adb8dbbf28a34f8574239a241e85d46f3877

    tool: Move ALIGN_MASK to header as common MACRO

    The ALIGN code is need by many files who need handle structure or image
    align, so move the macro to imagetool.h file.

The __ALIGN_MASK definition used  in imx8image was not standard, so I
restored it like this:

--- a/tools/imx8mimage.c
+++ b/tools/imx8mimage.c
@@ -32,6 +32,8 @@ static uint32_t rom_version = ROM_V1;

 #define HDMI_FW_SIZE           0x17000 /* Use Last 0x1000 for IVT and CSF */
 #define ALIGN_SIZE             0x1000
+#define ALIGN(x,a)                     __ALIGN_MASK((x),
(__typeof__(x))(a) - 1, a)
+#define __ALIGN_MASK(x,mask,mask2)     (((x) + (mask)) / (mask2) * (mask2))

 static uint32_t get_cfg_value(char *token, char *name,  int linenr)
 {

and now the board boots again:

I will submit the patch soon.

The issue now is that saving the environment to the SD card is no
longer working.

I will investigate the SD card issue now.

Thanks,
