From eaadb44edf6799099ee73d423bbfd5e33b8ee9ff Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 13 Sep 2010 11:10:34 +0200 Subject: [PATCH] cp/cmp: Add WATCHDOG_RESET in copy and compare loop On some boards with a very short watchdog timeout, the "cp" and "cmp" commands may reset the board. This patch adds some watchdog resets inside the loops. Otherwise for example the lwmon5 board will reset while doing something like this: => cp.b fc000000 1000000 100000 Signed-off-by: Stefan Roese --- common/cmd_mem.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/common/cmd_mem.c b/common/cmd_mem.c index 44834ea..f7a442a 100644 --- a/common/cmd_mem.c +++ b/common/cmd_mem.c @@ -337,6 +337,10 @@ int do_mem_cmp (cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) ngood++; addr1 += size; addr2 += size; + + /* reset watchdog from time to time */ + if ((count % (64 << 10)) == 0) + WATCHDOG_RESET(); } printf("Total of %ld %s%s were the same\n", @@ -447,6 +451,10 @@ int do_mem_cp ( cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) *((u_char *)dest) = *((u_char *)addr); addr += size; dest += size; + + /* reset watchdog from time to time */ + if ((count % (64 << 10)) == 0) + WATCHDOG_RESET(); } return 0; } -- 2.7.4
