Yes, these are the correct routines. Please make sure this code is running from RAM (i.e. not the flash) and make sure the time delays are accurate.
: to program the 2329 I use the the
: App125
: document, using the routines related
: to 0.35um, is this correct routines
: to program H8s/2329 ? .

: It sounds like your code did not
: program the flash correctly. Did
: you remember to use the
: program-verify feature of the
: programming algorithm and the
: erase-verify feature of the erase
: algorithm. If the contents were not
: versified correctly as given in the
: algorithm the data retension cannot
: be assumed to be that specified in
: the hardware manual. Also check
: that the re-program and additional
: re-program data is being correctly
: calculated. Apps note 125 from the
: link below should help.

: I made a program on 2329 boards, to
: manage a message display leds, this
: program has a feature that allows to
: change firmware at run time, erasing
: and writing 2329 flash memory, the
: program runs perfectly. these
: hardware had been stored during 6
: mounths, (there are 400 hardware
: cpus), and now, 6 mounths later 50
: cpus seem to be lost their flash
: program, seems as flash memory was
: erased.
:
: do you know why flash lost its data?
:
: thank you, very much in advance.
