I have an application that declares some longs as follows: long lCALC_L; long lCALC_E_y; When I build and compile with v3.4.1 I get the following in my map...
Hi Hugh, ... Yup - bug in gcc/config/arm/elf.h. The definition of ASM_OUTPUT_ALIGNED_COMMON is bogus. If you delete it (as has been done in the 3.4 sources)...
Hi All, because of some other linker problems I tried to update arm-elf-gcc from 3.2.1 to 3.4.1. after a few modifications in eCos I was able to build the eCos...
Hi All, I would like to specify that some statically allocated data should not be initialized by the startup boot code. This area will be in a battery backed...
... done ... Yes. I expect to be releasing a new GCC 3.4.1 toolchain with this fix (plus some nasty THUMB bug fixes) next week. As usual, I have been utterly...
... Why don't you use a pointer to your data instead? Else, you can always control the placement of symbols in your linker file. Just declare your variables in...
... Oops, I got it the other way around ;^) There are however some minor issues with GCC 3.4.1, so that 's why I expect to do an interim release soon. Regards....
Hi, Till I am not able to make initialization file for file hardening. I am using GNUARM compiler & ARM7tdmi evaluation board. If anyone have startup code for...
Hi Claudio, ... Yes. The section attribute can be applied to data. From the gcc documentation (gcc/doc/extend.texi:Variable Attributes): "Normally, the...
Hi Nick, Let me clarify my previous post: If I change buffer size to *anything else* than 128 (0x80) than the compiled result will be, as reported by .map...

It appears UART_TX_BUFFER_SIZE might be #defined before the compiler gets to the definition in globals.h. Try removing the #ifndef UART_TX_BUFFER_SIZE around...
Hi, Is it possible to reserve some memory in the linker script file ex: MEMORY { sram (WXAI) : org = 0x00000100, len = 256K - 0x100 flash (RX) : org =...
... Hi, ... yes, you only need to decrease the memory region. For example if your flash is 2 MB and you want to use only 1 MB because the other megabyte will...
Hi Bill, I did this first when I saw this [crazy allocation]. ... arm-elf-as -v -o start.o start.s GNU assembler version 2.15 (arm-elf) using BFD version...

Hello Nick, I did not give up, after all. I did dig more into it, made another var (buffer) at the same places as the UART_TX_BUFFER_0x80_sized was. Using the...
