The format of the Code Space of uPSD3200
2011-05-17 03:06 AM
I know there are several formats of file concerning the uPSD3200 programming.
The first one is hex-80, which is user's firmware and generated by a compiler such as KEIL; The seconde one is obj, which is the output file of PSDsoft Express after merging the hex-80 file above with PSD configuration file; But after downloading the obj file into uPSD3200, I find that the final data in the code space of uPSD3200 are different from the original obj file. Is it an another format? Anyone knows it in detail? or how can I know the size my obj file takes up in the code space of uPSD3200? So I can select enough sectors in the ''Merge MCU/DSP firmware with PSD'' step. Thanks in advance.2011-05-17 03:06 AM
hi,
- the obj-file contains all firmware, AND the configuration data for the PSD. - the hex-files contain the firmware (for the mcu) - this is what is written to the flash memory to determine the size of the firmware from the hex-file, you can look at the hex-file (i.e. see: for a specification), or you can convert the hex-file into a ''bin-file'' (i.e. by hex2bin, see the above website). the bin-file exactly contains what is written to the flash, and so the size of the bin-file is the size of the needed flash memory.2011-05-17 03:06 AM
oh, I see. Many thanks!
