Bootloader use compressed fonts:
The previous Bootloader was larger than 128k => not fitting into the first sectors of the second flash bank. Most memory is occupied by the two fonts in use. In order to make the bootloader small enough for the bootloader update function the fonts need to be compressed. To avoid code changes in visualization functions the compressed fonts are decompressed into RAM and then used in the same way as before.

# How to Make an Uploadable Firmware File for the OSTC4 # Generated BIN files from the SMT32 Workbench need modification in order to be installed via the OSTC Companion onto the OSTC4. ## Build Command Line Tools ## These can be found in /ostc4pack (For Windows, CPP sources available) ## Run the Tools Manually ## 1. Copy generated BIN files (From the Release or debug directory) into /ostc4pack. Or: Modify .bat files to point to your Release or debug directory. 2. run step1_create_OSTC_RTE_upload.bat and/or step1_create_OSTC4_firmware_upload_bin.bat (Depending on which part you made changes) 3. run step2_create_OSTC4update_bin.bat to create final OSTC4update_xxxxxx.bin, with xxxxxx being the current date in YYMMDD format. This will add important checksums required for the OSTC4's bootloader to accept the file. ## Upload this file with the OSTC Companion software to the OSTC4 ## See http://forum.heinrichsweikamp.com/read.php?7,19186 on how to get and use the "OSTC companion"
