From cbc3015878e547042b5ded7625ac3a1a45d6b7f0 Mon Sep 17 00:00:00 2001 From: Georg Lukas Date: Sat, 31 Jan 2009 02:08:31 +0100 Subject: [PATCH] added soft-reset command to ramtool and lpctool When no RTS/DTR lines are available (cell phone cable), a soft reset can be performed after a successful flash instead of an external reset. You have to open the EINT1 jumper during the flash process if you want to boot into the newly loaded firmware! --- lpctool.c | 3 +++ ramtool.c | 6 ++++++ toolcmd.h | 1 + 3 files changed, 10 insertions(+), 0 deletions(-) diff --git a/lpctool.c b/lpctool.c index 8a23a4a..1ed0b90 100644 --- a/lpctool.c +++ b/lpctool.c @@ -1,6 +1,7 @@ #include "infohelper.h" #include "lpctool_serial.h" #include "bootcom.h" +#include "toolcmd.h" #include "toolcom.h" #define VERSION_MAJOR 0 @@ -154,7 +155,9 @@ void enterBootLD(void) void resetFB(void) { + char reset_cmd = RESET_CMD; setDTR(1); + sendBuf(1, &reset_cmd); usleep(100); setDTR(0); } diff --git a/ramtool.c b/ramtool.c index e87ed45..d4a44f5 100644 --- a/ramtool.c +++ b/ramtool.c @@ -13,6 +13,8 @@ typedef volatile unsigned int *reg32_t; #include "toolcmd.h" #include "fonty.h" +void (*resetBL)(void) = (void (*)(void))0x7FFFE000; + union { unsigned long wbuf[128]; @@ -331,6 +333,10 @@ fail_f: serial_putc('\n'); } } + else if(i==RESET_CMD) + { + resetBL(); + } } return 0; } diff --git a/toolcmd.h b/toolcmd.h index 065ddd9..b25dccf 100644 --- a/toolcmd.h +++ b/toolcmd.h @@ -13,6 +13,7 @@ #define SETNUMBYTES_CMD 'S' #define READ_CMD 'R' #define SKIP_CMD '>' +#define RESET_CMD '*' #define HELOTOKEN "HELO" #define ACKTOKEN "ACK!" #define NACKTOKEN "NACK" -- 1.5.6.5
