v0.21 boots to black screen

[RonsCompVids]

After compiling v0.21, I am only able to get a black screen with a Happy Mac stuck in the middle. If I power on with the SD card removed (SD card contains a System 3.2 image bootable on previous builds), I will sometimes see a blinking question mark in the place of the Happy Mac.

Firmware was compiled without a baked in disk image... but was configured for 640x480, SD and 208k support.

Any clued on what might be wrong?

Thank you!

@RonsCompVids I have built v0.21 with SD card support and a built-in disk image and I have never attached a SD card so far, and have never seen this issue.

Does it also happen for you if you remove all SD card circuitry? Possibly it thinks there is a SD card but doesn't find one for some strange reason?

If you like, you can also test with my build that is the basis for this pull request:

I can certainly test it tonight.

I believe my error was not using the appropriate switched when compiling.
