PICO unable to access SDcard
Mikael Säker (2470) 6 posts |
I’m on a Raspberry Pi B+ and have gotten Pico up and running. However, I can’t find a way to access the contents of the SD card drive. From Basic: 1. *CAT returns “The disc drive is empty”. I’ve tried to put PICO on two different cards with the same results. Any pointers? Thanks, M |

The current Pico build is too old to contain proper support for the B+ (the SD card detect line was removed, so old builds will always complain that the drive is empty). I’m not sure if/when ROOL are planning on updating the build, but to be honest it’s not that hard to turn a regular Pi ROM into something that will boot into BASIC. All you need to do is enter the following at the CLI: *opt 4,0 *configure language 13 *configure mode 7 *unplug bootfx |

Cool, thanks. I’ll try that. Lots of new things to learn with this OS. :) M |

Equally it is easy to update the Pico firmware to use bootcode.bin start.elf and fixup.dat from the current RC12a image. |

Yeah, I tried that but unfortunately it doesn’t work. |

Hi Jeff, Entering those commands got me booting into basic but it doesn’t switch into mode 7 (it appears to be doing “Auto” which results in really tiny fonts). If I QUIT BASIC and doing *Status Mode is listed as 7 Any ideas Thanks Jonathan |

Hi Mikael, I had exactly the same problems on RPi B+, until I found an updated version of Pico at http://packages.riscosopen.org/RISC-OS_Pico.zip I also had to add the following line to CONFIG.TXT to get rid of some issues with screen display: hdmi_safe=1 Now everything works perfectly. |
