QORC SDK v1.10.0 Release

This release added support for

• AEC development example project qf_vr_apps/qf_vr_aec_app

QORC SDK v1.5.0 Release

This release enhanced the bootloader application to version v2.1 with ability to read application FPGA binary from flash and load it to the device. The release added several example and test application projects. The changes are listed below:

1. [Bootloader FPGA Loading] Enhanced bootloader projects to load application FPGA binary.
   The following test applications are provided to show usage of loading FPGA binary
   • qf_advance_fpga_separate for building and loading an FPGA binary and M4 application binary using the enhanced bootloader v2.1
   • qf_helloworldsw_separate for loading an FPGA binary and M4 application binary using the enhanced bootloader v2.1
     Using the enhanced bootloader requires updating to the
   • QuickLogic FPGA toolchain v1.3.1
   • QuickLogic TinyFPGA-Application-Programmer version QL-v2.0.0
2. Voice-recognition Opus streaming example application project
3. Simple Streaming Interface SensiML AI application project
   Bootloader over UART project that receives application binary over the S3 UART interface and similarly Loadflash over UART project that receives application binary over S3 UART interface

QORC SDK v1.4.0 Release

This release added support for multiple instances of UART and GPIO gateware module and several example application projects listed below:

1. [2-Mic Voice-recognition example] application project and VR raw streaming example application project
2. Bootloader over UART project that receives application binary over the S3 UART interface and similarly Loadflash over UART project that receives application binary over S3 UART interface
3. FPGA UART example usage application project
4. Gateware test harness example project to validate new gateware projects using a QORC-SDK Command Line Interface (CLI)

New gateware modules and projects

• gpio gateware module
• uart gateware module
• gpio+uart gateware project
