ReAl

A strange bug was found in avreal 1.28r2 and 1.28r3. At the coincidence of conditions

• An FT2232/FT4232-based adapter is used
• There are some data for top two flash bytes — either data from hex-file or erase counter
• flash and fuses are used in one avreal call
• -v verification switch is used

for some microcontroller types avreal fails with “synchronosation lost” error after the first verification.

Working of avreal with FT2232C/L/D/H has been checked for WindowsXP/64, Windows7/32 Windows7/64 and CDM 2.06.00 driver. All OK.

avreal v1.28r1 (Sun 2010-01-31) has been released.

• FT2232H, FT4232H support is added. Both channels with MPSSE are allowed for programming. Allowable pin names are listed in configuration description.
• Switch -k is added for waiting an adapter’s key being pressed before starting the programming. See key record description.
• Switch modifier -os is added for selecting SCK frequency instead of MCU clocking frequency.

avreal v1.28r0 (Wed 2010-01-20) has been released.

• FTDI device list switch -aft2232 -p? doesn’t require microcontroller type switch +name.
• tiny2313A, tiny4313 added.
• -az switch leaves FT2232 in MPSSE mode with programming pins configured as inputs.
• Pin groups led_ok, led_error are added for LPT-based adapters.
• All record types including led_ok, led_error are supported now for FT2232-based adapter configuration.
• enable pin for FT2232-based adapters is processed in the same way as for LPT-based so inversion mark ‘~’ is required for buffers with active low enable input.
• Unbuffered mode is always used for program output for better information refreshing when IDE redirection is used.
• HEX-file data records (type 00) with zero-length data field are ignored.
• -ar switch was removed so configuration file must be created for inverted RESET.
