it's big soft, with many files ... see below for the structure
declaration.

is : arm-softfloat-linux-gcc -wall -O3 -msoftoat.

good remark ! Yes I've tested it , and it's working well on my host PC !

Do you are using anywhere else in your sources a variable also called tSytgeoBus with a different size? For global common variables the linker combines them into one variable. So: source1.c [...] int var; [...] source2.c [...] char var; [...] source3.c [...] long var; [...] ...all different var will be combined into one variable var by the linker. Try to add the --warn-common parameter to your linker. This will help to find such an failure. Hope it helps Juergen -- Dipl.-Ing.

Re: [ptxdist] memory problem with my soft
the memory problem is that the ucState variable in the global structure can be bad ( the max value should be 6 and I found 80 or 254 or 16 ) !
