-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi,
First of all, thank you for your answers (Michiel and JMGross). You both assumed that I've tried to use more than 64KB, but I didn't do it yet. The only thing I have tried was to install MSP430X and compile a simple program with around 16KB, what resulted in a strange behavior that looks like reset. - From this I can conclude that the new Assembly opcodes cause trouble even if everything is below 64KB. As Michiel told me, if I try to use the -mdata-64k it should work but that's not the case. The only way of making it work was to use both -mdata-64k and -mcode-64k. If I try to use only -mcode-64k, I get problems with variables (for instance when trying to print an integer) but the board doesn't enter the reset state. In the opposite, if I use only -mdata-64k the board keeps resetting as before. Is there anything I can do? I've checked the generated Assembly without those -mdata-64k and -mcode-64k flags and it looks like that the new opcodes are in use everywhere (for instance, CALLA and RETA).
