[avrdude-dev] [bug #41561] AVRDUDE 6.0.1/USBasp doesn't write first bytes of flash page

[Randy Perkins]

Follow-up Comment #15, bug #41561 (project avrdude):

When writing to an M64 MCU the output of -vvvv does not seem correct for a
paged write when compared to other processors.  the page size is 256 but the
software is not writing 256 at one time.

The relevant section of the -vvvv output is pasted here.  attached is the
entire -vvvv output and the hex file that was attempted to be written.  The
hex file was created to be easy to track the pages, but is not something the
MCU would actually run.
