marqs cbe2611471 fix OSD size in interlace passthru mode 2021-07-31 18:13:22 +03:00
Ari Sundholm 760be1738e Userdata export (FAT16): Optimize code size. 
Reorganize the and optimize the code to avoid redundant code and thus
reduce code size, while making sure to zero-initialize the used areas
on the SD card. These are the "clean" part of this change.

The "dirty" part:
Optimize the FAT16 export code further by introducing small deviations
from the FAT16 specification. These deviations should not be harmful
at all, unless the SD card is used for something requiring the jump
instruction and/or boot code in the boot sector to be valid. This is
typically only required when booting off the filesystem.

After these changes, a considerable reduction in code size can be
observed for sys_controller.elf and sys_onchip_memory2_0.bin:

sys_controller.elf:
   text	   data	    bss	    dec	    hex	filename
  32392	   2936	   2652	  37980	   945c	sys_controller.elf

sys_onchip_memory2_0.bin:
size: 35328 bytes

This reduces the cost of the FAT16 export feature to 446 bytes.

Ari Sundholm 32bbc49bf0 Userdata export: Fix menu behavior, particularly with the OSD. 
The behavior of the menu option was all over the place, and would
easily leave the OSD in a weird state, requiring the user to blindly
do something that completely redraws the OSD.

Fix this by making the behavior similar to that of the userdata import
feature, with the difference of giving a more specific error message
when something goes wrong.

Ari Sundholm b890446e3d Implement userdata export. 
A very simple implementation, as we are very short on remaining
block RAM. Simply blindly copies the entire userdata area to the
SD card. This may subject the SD card to some extra wear, as well
as potentially read-disturb some Flash memory pages, but this would
require more code.
