From 58d958e60c429bd7a2b2d114a4f7a86a65bdacef Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Sat, 30 Jul 2011 02:56:36 +0200 Subject: DFU: Support re-flashing of DFU via DFU As we re-locate the entire sam7dfu program into RAM, we don't need to execute from flash and can thus re-program the DFU partition via the DFU protocol itself (alternate setting '1'). We also implement downloading executable code into RAM using alternate setting '2'. The latter part is not properly executed yet. --- firmware/link/AT91SAM7S128-RAM-sam7dfu-app.ld | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'firmware/link') diff --git a/firmware/link/AT91SAM7S128-RAM-sam7dfu-app.ld b/firmware/link/AT91SAM7S128-RAM-sam7dfu-app.ld index 674ee00..ad02776 100644 --- a/firmware/link/AT91SAM7S128-RAM-sam7dfu-app.ld +++ b/firmware/link/AT91SAM7S128-RAM-sam7dfu-app.ld @@ -5,7 +5,7 @@ MEMORY /* reserve 16K DFU area on top of flash */ /* FLASH (rx) : ORIGIN = 0x00104000, LENGTH = (0x00020000 - 0x4000 - 0x400) */ /* reserve 1k DFU area on top of RAM */ - DATA (rw) : ORIGIN = 0x00200400, LENGTH = (0x00008000 - 0x400) + DATA (rw) : ORIGIN = 0x00202000, LENGTH = (0x00008000 - 0x2000) STACK (rw) : ORIGIN = 0x00208000, LENGTH = 0x00000000 } @@ -16,7 +16,7 @@ SECTIONS { . = 0x00000000; /* first section is .text which is used for code */ - .text 0x00200400: AT ( 0x00000000 ) { + .text 0x00202000: AT ( 0x00000000 ) { src/start/Cstartup_app.o (.text) * (.text) * (.rodata*) -- cgit v1.2.3
