ubootlua's Issues

Increase CODE area in boot

Executing code with a image >47k:

WARNING: Image format was not specified for './deploy/boot.bin' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.
