From fa956af92c4c278187fa97d445100a7df62a9f90 Mon Sep 17 00:00:00 2001 From: "Brian S. Dean" Date: Thu, 14 Feb 2002 02:48:07 +0000 Subject: [PATCH] Fix error reporting by avr_write_byte(). Fix setting of status LEDs under various write-fail conditions. Add a flag to indicate that a memory type requires the device to possibly be powered off and back on after a write to it. This is due to a hardware problem on some Atmel devices, see: http://www.atmel.com/atmel/acrobat/doc1280.pdf Add greater verbosity to the part-display code when verbose>1 to display avrprog's encoding of the defined programming instructions. This is primarily for debugging purposes. Part updates: * add the AT90S4414 part * add fuse and lock bit access instructions for the AT90S1200, AT90S4434, and AT90S8515. * add the pwroff_after_write flag to the fuse bits for the AT90S2333 and AT90S4433 parts git-svn-id: svn://svn.savannah.nongnu.org/avrdude/trunk/avrdude@123 81a1dc3b-b13d-400b-aceb-764788c761c2 --- avr.c | 146 ++++++++++++++++++++++++++++++++++++++------ avr.h | 8 ++- avrdude.conf.sample | 114 ++++++++++++++++++++++++++++++++++ config_gram.y | 7 +++ lexer.l | 1 + main.c | 2 +- term.c | 18 ++++-- 7 files changed, 273 insertions(+), 23 deletions(-) diff --git a/avr.c b/avr.c index 2c3937e6..2c8d3b58 100644 --- a/avr.c +++ b/avr.c @@ -442,8 +442,9 @@ int avr_read(int fd, AVRPART * p, char * memtype, int size, int verbose) } buf[i] = rbyte; if (verbose) { - if ((i % 16 == 0)||(i == (size-1))) - fprintf(stderr, " \r%4lu 0x%02x", i, rbyte); + if ((i % 16 == 0)||(i == (size-1))) { + fprintf(stderr, "\r \r%6lu", i); + } } } @@ -524,7 +525,7 @@ int avr_write_byte(int fd, AVRPART * p, AVRMEM * mem, rc = avr_read_byte(fd, p, mem, addr, &b); if (rc != 0) { if (rc != -1) { - return -1; + return -2; } /* * the read operation is not support on this memory type @@ -603,11 +604,14 @@ int avr_write_byte(int fd, AVRPART * p, AVRMEM * mem, tries = 0; ready = 0; while (!ready) { - usleep(mem->min_write_delay); /* typical write delay */ + usleep(mem->min_write_delay); rc = avr_read_byte(fd, p, mem, addr, &r); if (rc != 0) { - return -1; + LED_OFF(fd, pgm->pinno[PIN_LED_PGM]); + LED_ON(fd, pgm->pinno[PIN_LED_ERR]); + return -4; } + if ((data == mem->readback[0]) || (data == mem->readback[1])) { /* @@ -619,24 +623,62 @@ int avr_write_byte(int fd, AVRPART * p, AVRMEM * mem, usleep(mem->max_write_delay); rc = avr_read_byte(fd, p, mem, addr, &r); if (rc != 0) { - return -1; + LED_OFF(fd, pgm->pinno[PIN_LED_PGM]); + LED_ON(fd, pgm->pinno[PIN_LED_ERR]); + return -5; } } if (r == data) { ready = 1; } - + else if (mem->pwroff_after_write) { + /* + * The device has been flagged as power-off after write to this + * memory type.
