Just asking - is for file for the HDMI version (it is just called PicoMite)? For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

Yes, it works great now.  PicoMiteHDMI MMBasic RP2350A Edition V6.00.01RC8 OPTION FLASH SIZE 4194304 OPTION COLOURCODE ON OPTION KEYBOARD US OPTION KEYBOARD PINS GP2,GP3 OPTION CPUSPEED (KHz) 315000 OPTION HDMI PINS 1, 3, 5, 7 OPTION SDCARD GP5, GP6, GP7, GP4 OPTION AUDIO GP10,GP11', ON PWM CHANNEL 5 OPTION PSRAM PIN GP8 Now, I have another question about PSRAM, how can I now disable it without resetting other settings options? |

Have you tried OPTION PSRAM DISABLE ? Then again, just disconnecting it from GP8 will remove its CS signal and it's gone. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

OPTION PSRAM DISABLE does not work, there is no such OPTION. I modified my RP2350-Plus board with a jumper that disconnects CS from the PSRAM chip. Disabling this signal CS subsequently led to a complete system freeze. I had to erase and reflash "Pico2" again, restore the option settings.  By the way, can someone help write a stress test or a performance test for this type of PSRAM memory with a capacity of 8 Mbytes?  Edited 2024-12-18 10:10 by javavi |

Hi Javavi, Disconnecting is not enough. You may need a pull-up on the chip to make sure the cs pin is off. I tested PSRAM by DIM of a huge array. Filling that with random data in a loop is basically a memory test. i.e. 800000 elements (=800000 * 8 bytes = 6.4Mbyte). You can also use ppre-defined data (&haaaaaaaa and &h55555555) and verifty the data by reading it. If you run the same test with 8000 elements in the array (8000 elements = 64kbyte = fit in RP2350 RAM) you will notice that the speed of MMBasic is significantly higher (per array cell changed) than when executing the same routine with 800000 elements. So PSRAM is slower. I measured PSRAM to be 10x slower in earlier tests. Volhout Edited 2024-12-18 17:16 by Volhout PicomiteVGA PETSCII ROBOTS |

To test that without adding a resistor replace the jumper then:- SetPin GP8, DOut : Pin(GP8) = 1 Though you will need to remove OPTION PSRAM from the options. If OPTION PSRAM DISABLE doesn't work trial and error may be needed. eg OPTION PSRAM OFF or DELETE or REMOVE etc. Failing that reset all the Options. Edited 2024-12-18 17:19 by phil99 |

Hi phill, That may not work. When PSRAM blocks the flash SPI bus, you cannot get into MMBAsic at all. Volhout PicomiteVGA PETSCII ROBOTS |

Hi Peter, I tried it and the first half (16 bytes) worked. Could it be that I made another mistake? I chose the "ECB" mode and omitted the initialization vector. To check it I took the key (0x01 - 0x10) and the data (0x01 - 0x20). Dim float key(15)=(&H01,&H02,&H03,&H04,&H05,&H06,&H07,&H08,&H09,&H0A,&H0B,&H0C,&H0D,&H0E,&H0F,&H10) Dim integer in(63),out(63),comp(63) Dim integer iv(15) Dim s$="" Dim k$="" Data &H01,&H02,&H03,&H04,&H05,&H06,&H07,&H08,&H09,&H0A,&H0B,&H0C,&H0D,&H0E,&H0F,&H10 Data &H11,&H12,&H13,&H14,&H15,&H16,&H17,&H18,&H19,&H1A,&H1B,&H1C,&H1D,&H1E,&H1F,&H20 ' Key Print "Key:" For i=0 To 15 Print Hex$(key(i)); " " ; Next 'read in the message to be encrypted For i=0 To 31 Read in(i) Next 'convert the key array to a string version of the key 'For i=0 To 15 ' iv(i)=15-i 'create an initialisation vector different from the default ' Inc s$,Chr$(key(i)) 'Next 'convert the message to a string version of the message 'For i=0 To 31 ' Inc k$,Chr$(in(i)) 'Next ' encrypt the message Math aes128 encrypt ecb key(),in(),out() Print "Input text:" For i = 0 To 31 Print Hex$(in(i)); " " ; Next i Print "Encrypted text:" For i = 0 To 31 Print Hex$(out(i)); " " ; Next i End Result : Key: 1 2 3 4 5 6 7 8 9 A B C D E F 10 Input text: 1 2 3 4 5 6 7 8 9 A B C D E F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 Encrypted text: 34 C3 3B 7F 14 FD 53 DC EA 25 E0 1A 2 E1 67 27 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F 20 Cheers Bishop |

Bishop I've checked the TinyAES source and it only converts 16 bytes at a time. I'll put a loop in my code but in the meantime you should find that doing your 32-byte message 16 bytes at a time should work. twofingers Can't replicate. MM.ENDFILE$ is automatically created by the END statement and works for me. |

> OPTION PSRAM DISABLE Error : Invalid Option  > OPTION PSRAM PIN DISABLE  On my "Pico2" module I have a jumper to pin 1 (CS) of the PSRAM which is pulled up by a 10k resistor to the chip power supply. If the PSRAM is connected and the OPTION PSRAM PIN GPn is configured, then everything works. But if you remove the CS jumper and turn on the power, then everything freezes, and returning the jumper does not change anything. Only erasing and reflashing with the CS jumper disconnected restores startup. Is it possible to introduce some kind of check for the presence of the PSRAM at startup and if it is not detected, then disable it or not use it? |
