Hey fellows,
im using the code from shabaz BBB - High speed data acquisition and web-based UI <http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone/blog/2013/08/04/bbb--high-speed-data-acquisition-and-web-based-ui> article and I did a rewrite of the PRU programm in C to fit it on the ADC. I wrote and tested the program in CCS over JTAG and it works quiet well. Also the shared RAM writing seems to work. Then I took the code onto the BBB with Ubuntu, installed the PRU C-Compiler for ARM etc... The compiler- and linkerflags are (taken from the CCS makefile): CLPRUFLAGS = -v3 -g -k -I"./lib" -I"./include" CLPRULINKERFLAGS = --run_linker --define=am3359 -m"pru_code.map" --define=pru0 --diag_warning=225 --display_error_number --diag_wrap=off --heap_size=0x100 --stack_size=0x100 --reread_libs --define=PRU_CORE=1 --warn_sections --rom_model --xml_link_info="pru_code.xml" -o pru_code.bin link.cmd Then I modified the the adc.c host program for loading into PRU0 because of the PINs I wired the ADC to. I also did the stuff with the device tree etc. Now, when I run the host program it stops at prussdrv_exec_program (PRU_NUM, "./pru_code.bin"); with the buffer overflow message I mentioned in the subject. What does that mean? Even google finds only one slightly usefull comment on a blogpost... I attached the source of the hostprogramm. Kind regards, Philipp P.S.: I discoverd that the size of the PRU programm compiled on the BBB is bigger (46kB) than the Version compiled in CCS on my Windows machine (32kB). -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
