Compiled with [sdcc](http://sdcc.sourceforge.net/), we call it sdfirm. Unlike other small device firmware architecture (sdcc or avr-libc), sdfirm does not require libc to be linked. + +Our mission is to add following features for this firmware, others are left for you to extend: +<pre>1. supported architectures + 1.1. MCS51 support with SDCC compiler + 1.2. AVR support with GCC compiler + 1.3. ARM support with GCC EABI compiler +2. supported simulators + 2.1. OpenOCD configuration for some boards +3. timing facilities (delay, timer, jiffies) + There are tow kinds of timing devices supported: + 4.1. TSC (like linux's clock source device) + 4.2. GPT (like linux's clock event device) + Following timing features are not yet implemented: + 4.3. realtime time axis (not supported due to lack of RTC and usable TSC) + 4.4. interrupt context timeout event +4. state machine machnism (like linux's soft IRQ) +5. USB device protocol stack + Following USB features are implemented: + 6.1. control endpoint + 6.2. bulk/interrupt endpoints + 6.3. pipe halting (reset recovery, unhalt recovery) + 6.4. synchronous/asynchronous pipe IO + Following USB features are not yet implemented: + 6.5. buffering (global single buffering, local single buffering, local double buffering) + 6.6. isochronous endpoints + 6.7. bi-directional endpoints +6. Smart card interface devices protocol stack + Following IFD features are implemented: + 6.1. ISO7816-3 support + 6.1.1. protocols: T=0, T=1 + 6.1.2. exchanges: TPDU level, short APUD level + 6.1.3. auto sequences + 6.2. USB CCID and ICCD support + Following IFD features are not yet implemented: + 6.3. ISO7816-4 support + 6.4. ISO14443 support + 6.5. ISO18092 support +7. SCSI device protocol stack + Following SCSI features are implemented: + 6.1. SAM and SPC support + 6.2. SBC support + 6.3. USB MSD support + There are still needs for performance tuning on MTD devices. +8. Networking + This has been in the plan for months, but not yet implemented.</pre> + +This project is released under GPLv2.
