Sasquatch, Try option reset. Option flash size is set automatically and reports the size of the flash chip if not 2Mb Edited 2024-08-27 03:34 by matherp |

Thanks Peter, the Flash Nuke seems to have fixed my Pico2 running standard HDMI. However, I was using GP8 and GP9 for my SD (just picked at random) but when I try to enable my SD with:- OPTION SDCARD gp11,gp10,gp9,gp8 I get an error, GP8 is already allocated, OPTION LIST doesn't show anything using GP8 so I tried:- OPTION SERIAL CONSOLE DISABLE which went away and did something, but trying again with the SDCARD definition got the same error; on the USB version, this had worked. I didn't think the standard version pre-allocated GP8 & GP9? Anyway for now I've moved to GP6 & GP7, which is currently working fine. Regards, Kevin. |

Same result after option reset. Not surprisingly same result with VGA version on RP2350B. No worries, we had to expect a few warts this early in the game. I'm working on connecting my RP2350B PGA board for HDMI. -Carl |

Gp8 and 9 are the PS2 keyboard, disable this if you want to use them for anything else, see VGA manual. Same as rp2040 vga. I think I know what the problem is with the VGA version but can't fix until later in the week. Edited 2024-08-27 05:03 by matherp |

Hi Peter, Another problem I think. If I do something like Mode 2 Framebuffer layer 9 'set transparent colour Framebuffer write n 'write to display Load image "xyz.bmp" 'load a full screen bitmap Framebuffer write l:cls 'write to layer, clear layer to colour 9 transparent Load image "pqr.bmp",70,50 'load smaller bitmap over top of display But what actually happens is the CLS clears to black, so only the second loaded bitmap is displayed on a black background. If I specify CLS RGB(magenta) it works as it should. Only tested on HDMI so far. Regards Kevin. |

Hi Kevin, I think rp2040 mmbasic works the same. Volhout PicomiteVGA PETSCII ROBOTS |

Hi Harm, I found this from Martin's VGA version of FlappyBird, it works on 2040, but didn't work on 2350, just the start up screen, plus the manual I have implies a CLS on a layer should clear to the layer defined background volour. Regards Kevin Edited 2024-08-27 17:28 by Bleep |

Just tested it on 2040, and yes, you are right. CLS should clear to background color unless specified different. Volhout Edited 2024-08-27 17:37 by Volhout PicomiteVGA PETSCII ROBOTS |

Hi Peter Thanks for creating the new RP2350 firmware versions. after playing around a bit with the hdmi version... Is it right that there are still just Mode 1 and 2 ? Can you give a short diskription, how to use the MAP Command to redefine the Colors Cheers Martin 'no comment |
||||
| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 9105 |
At the moment just modes 1&2. In mode 1 you can specify RGB888 colours for the tiles. These will be converted to RGB555 for display. See he PicoMiteHDMI firmware - first cut thread for how to use the map command and function |

Hi - can I assume that I still need the PWM filter circuit as used on the 2040 designs, or does the 2350 chip have a special audio output? Smoke makes things work. When the smoke gets out, it stops! |

There's no special audio output and you still need the filter as before. Of course, you can also use a SPI DAC chip to do away with the filter. It used to put a bit of a load on the RP2040 CPU but I suspect it should be better on the RP2350. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Peter, Not sure if I am the first one to test. When I install the PicoMiteVGA-RP2350-V6.0.0B0.uf2 on a Pico-2 board, and plug it into my PicoMiteVGA platform (your design version 1.7) it gives video. FYI, I nuked the flash before installing. When I want to set cpuspeed to 252MHz (or any other option like option system I2C, I get an error message: PicoMiteVGA MMBasic Version 6.00.00b0 OPTION FLASH SIZE 4194304 OPTION KEYBOARD US > option cpuspeed 252000 Error : Stack overflow, expression too complex at depth 0 Other tests I have done are on the non-VGA PicoMite-RP2350-V6.0.0B0.uf2 (not played with options). All of the PIO code I tested runs 1:1 (this includes assembler and program instructions). I will look at the 3'rd PIO later today on the VGA version (that is probably 126MHz). I looked at speed using Mandelbroth, but compared to the 2040 (133MHz) the 2350 (150MHz) is equally fast (just the clock speed ratio). So I do not see the speed advance from the M33 core and hardware float support. But maybe this is not a fair test. Maybe Mandebroth just touches one aspect where both cores are the same.

I've done something stupid with the VGA version. Will update when home later this week. |

I found another bug. In the normal image PicoMite-RP2350-V6.0.0B0.uf2 When I run my frequency counter program, in essence it works. But it stops working after 1 sec ... 1 minute. The program has 1 PIO running(4 state machines) and controls/reads them via MMBasic RX and TX FIFO's. The measred frequency is send through USB console in text form to PUTTY or the likes. The MMBasic program stalls (in a loop it starts the PIO gate generator, and the gate signal is not generated anmore). The USB console interface does not accept <ctlr-C> anymore, so I cannot give any commands. Re-powering is the solution. Connect a LED to GP2 (PIO gate signal). While flashing, the counter works. If you want text output that makes sense (not 0), connect GP5 to GP0 with a dupont wire. This code works fine (for hours and hours) on RC2040 V5.09.00RC5 (my last version). freq_counter13_u.zip If you have suggestions how I can help debugging, just post here...

Pico Plus 2 doesn't like 378MHz (different flash?) 300MHz is no problem. |
||||
| Volhout Guru Joined: 05/03/2018 Location: NetherlandsPosts: 4222 |
It was to be expected. In Pico2 the QSPI bus is between RP2350 and flash chip. In Pico2-plus the QSPI bus is going from RP2350 to 2 devices 1/flash and 2/PSRAM. The extra load (PSRAM) may limit the speed at which the bus can be used. Even if the PSRAM is not used, it loads the bus. I hope it also works at 315MHz, since that is the CPU clock needed for HDMI. If not, HDMI is not possible at the Pico2-PLus. That would be a problem. Volhout Edited 2024-08-28 21:42 by Volhout PicomiteVGA PETSCII ROBOTS |

@Peter, I have succesfully run programs on PIO2 (next to PIO0 and PIO1). So that part is implemented well. Did you also implement the new MOV instructions in the assembler ? How are the mnemonics ? (MOVRX ?) By the way, these new instrcutions are actually quite interesting. In RP2040 we have (to make sure you have the latest value PIO generated) to read whole FIFO, and 1 beyond. In RP2350 we can make the PIO write the latest value always on FIFO location 0. So we need only read 1 FIFO register. Regards, Volhout Edited 2024-08-28 21:50 by Volhout PicomiteVGA PETSCII ROBOTS |
