Hello all, after I searched through the forums and tried different options to no avail I would like to ask here for an opinion My problem is programming a papilio one 500 SPI Flash within Linux, esp. Kubuntu 13.10 Flash works ok and the papilio-loader-gui shows no errors For me all looks good so far. I disconnected and reconnected the USB cable without success. Within a Win 7 64bit everything works like a charm (that is Flash and SPI are configured successfully) Any ideas? Thank you for reading Best regards Peter Using devlist.txtJTAG chainpos: 0 Device IDCODE = 0x41c22093 Desc: XC3S500EUsing devlist.txtJTAG chainpos: 0 Device IDCODE = 0x41c22093 Desc: XC3S500EUploading "/opt/GadgetFactory/papilio-loader/programmer/bscan_spi_xc3s500e.bit".
