- The post-reset delay of both the IDE and PPIDE drivers has been extended. The SD-IDE adapters need more time to initialize before being ready to behave as proper IDE devices.
- Added support for the FDC section of the Duodyne Disk-IO board.
- Added support for Duodyne Multi-IO board
- Added support for Duodyne Zilog-IO board
- Added SUPCTS equate in hbios.asm to allow selectively adding code to suppress use of CTS during HBIOS boot
- Added reference in User Guide to Bruce Hall's Assembly Language Programming document
- Detect CTS at startup to ensure it is asserted. If not, disable hardware flow control to avoid stalling the console at boot. Only for UART driver because this is the only place it is currently relevant.
- The build process was enhanced by Dean Jenkins to support the Raspberry Pi. Note that the Propeller firmware will not be generated by a RPi build. See Issue #358.
- Initial support for USB storage via CH375/6.
- Based on reports from Martin R, the FDC detection algorithm has been updated to try reading the FDC MSR register twice to try and get the desired value of 0x80.
- Dan Werner's ESP board for Duodyne is working well, so the default Duodyne config has been changed to automatically detect this board.
- Updated S100 Monitor launch code to warn user if console will be directed to S100 bus vs. active on-board UART.
- Updated Duodyne early boot to add a delay to stabilize the boot process. This is temporary and needs to be further investigated.
Added a new driver category for DSKY (Display/Keypad) devices. Existing DSKY devices were converted into drivers ICM and PKD. These devices were previously DSKY and DSKYNG.
This removes substantial code duplication and recovers significant space in romldr and dbgmon.
- Added ability to enable VGARC and front panel in default config without I/O conflicts (does **not** support having both types of hardware present at the same time).
- Fixed documentation error in issue #345 reported by @MorfeoMatrixx.
- Floppy devices are now configured per-device so that each floppy drive can be different (e.g., first floppy is 3.5" and second floppy is 5.25").
- Removed need to use termination signal on floppy sector I/O.
Addresses issue #318
Added configuration setting VDAEMU_SERKBD which can be used to specify any serial unit # to be used as the keyboard for the video terminal. Default value is $FF which means to use the default hardware keyboard. All other values mean that terminal input is to come from corresponding serial unit #.
Also a couple more tweaks to the p-System boot volume.
I got a very nice email from Eluan Miranda. He pointed out a few inconsistencies in the video and audio driver configurations. I made a few adjustments to clean things up.
- Update MFPIC related I/O ports from $4x to $1x. The default base address was changed to avoid conflicting with the default I/O range of $40-$7F on ECB Z180 boards.
