From bd88dfe418b4d3ec06cf283c9af55fef5098e56e Mon Sep 17 00:00:00 2001 From: Pablo Cossutta Date: Sat, 27 Apr 2019 19:33:07 -0300 Subject: Add -X option to iceprog In my setup, in OSX I have problems reading from libftdi but not writing. In case of a failure iceprog exits and leaves the FPGA in an useless state. I think it would be a good option to have the possibility to skip the verification process. --- iceprog/iceprog.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'iceprog/iceprog.c') diff --git a/iceprog/iceprog.c b/iceprog/iceprog.c index f9d1187..bae9e71 100644 --- a/iceprog/iceprog.c +++ b/iceprog/iceprog.c @@ -449,6 +449,7 @@ static void help(const char *progname) fprintf(stderr, "\n"); fprintf(stderr, "Mode of operation:\n"); fprintf(stderr, " [default] write file contents to flash, then verify\n"); + fprintf(stderr, " -X write file contents to flash only\n"); fprintf(stderr, " -r read first 256 kB from flash and write to file\n"); fprintf(stderr, " -R read the specified number of bytes from flash\n"); fprintf(stderr, " (append 'k' to the argument for size in kilobytes,\n"); @@ -517,6 +518,7 @@ int main(int argc, char **argv) bool test_mode = false; bool slow_clock = false; bool disable_protect = false; + bool disable_verify = false; const char *filename = NULL; const char *devstr = NULL; int ifnum = 0; @@ -529,7 +531,7 @@ int main(int argc, char **argv) /* Decode command line parameters */ int opt; char *endptr; - while ((opt = getopt_long(argc, argv, "d:I:rR:e:o:cbnStvsp", long_options, NULL)) != -1) { + while ((opt = getopt_long(argc, argv, "d:I:rR:e:o:cbnStvspX", long_options, NULL)) != -1) { switch (opt) { case 'd': /* device string */ devstr = optarg; @@ -616,6 +618,9 @@ int main(int argc, char **argv) case 'p': /* disable flash protect before erase/write */ disable_protect = true; break; + case 'X': /* disable verification */ + disable_verify = true; + break; case -2: help(argv[0]); return EXIT_SUCCESS; @@ -921,7 +926,7 @@ int main(int argc, char **argv) flash_read(rw_offset + addr, buffer, 256); fwrite(buffer, read_size - addr > 256 ? 256 : read_size - addr, 1, f); } - } else if (!erase_mode) { + } else if (!erase_mode && !disable_verify) { fprintf(stderr, "reading..\n"); for (int addr = 0; true; addr += 256) { uint8_t buffer_flash[256], buffer_file[256]; -- cgit v1.2.3
