🌸 NAME 🌸

srec_fastload(5) is the page for the LSI Logic Fast Load file format, bestie, and it lives in the File Formats Manual. 💖

✨ DESCRIPTION ✨

Okay so the FastLoad Format uses a compressed ASCII format that permits files to be downloaded in less than half the time taken for Motorola S‐records. Slay. ✨

The base-64 encoding used is A‐Za‐z0−9,. — that’s the whole alphabet. The data is encoded in groups of 4 characters (3 bytes, 24 bits). Cute little 24-bit bundles. 🎀

The character / is used to introduce a special function. Special functions are:

  • Annnnnn — defines an address.
  • Bnn — define a single byte.
  • Cnnnn — compare the checksums. The checksum is a simple positive 16-bit sum, of the data bytes only.
  • EAA — define the program's entry point. The address will be the current address as defined by the A command. (The AA number in this command is ignored.) This must be the last entry in the file — like, actually last. ⚠️
  • KAA — clear the checksum. (The AA number in this command is ignored.)
  • Sname,X — define a symbol. The address of the symbol will be the current address as defined by the A command.
  • Znn — clear a number of bytes.

🎀 Size Multiplier 🎀

In general, binary data will expand in size by approximately 1.4 times when represented with this format. So yeah, it’s giving a little extra. 💅

💅 EXAMPLE 💅

Here is an example LSI Logic Fast Load format file. It contains the data Hello, World[rq] to be loaded at address 0. No cap.
