Question: using the T_4.1 with SPI PJRC memory board wondering why these { "nand1","nand2" } ( the large 128 and 256 MB nand's ) are not presented on MTP Just the above noted 64MB #3 and #4?
- is the driver not taking these larger NAND's?
Reading the SerMon now it shows this at 33 and 25 MHz SPI speed:
Code:
SPIFlash Storage 0 3 nand1 failed or missing
SPIFlash Storage 1 4 nand2 failed or missing
I put an SDIO card in and it shows the files and it very quickly and usable updated and copied 'audio...PDF' to "This PC\Teensy\sdio"
I just deleted the above copied 'AUDIO...PDF' ( SDIO, NAND's, QSPI ) test files and all deletes worked with an explorer refresh showing the empty or remaining files as expected.
ERROR file not removed on SDIO card: On restart the 'AUDIO...PDF' file is still present on Reset of the Teensy.
>> Second restart still shows 'Audio_workshop.pdf' among the listed files and the file is still intact and readable.
- > the SD card is a 32GB card that has other files ( mostly WAV files ) used in other Teensy testing.
>> Files were removed from the SPI NAND media and the QSPI flash.
Using LOGLOW T_4.0 with SDIO and Audio card with FLASH and SPI SD card:
Code needs to not define QSPI when using T_4.0 - it hangs after showing the 2 SD cards:
Code:
#ifdef ARDUINO_TEENSY41
#define USE_LFS_RAM 1 // T4.1 PSRAM (or RAM)
[B]#define USE_LFS_QSPI 1 // T4.1 QSPI[/B]
#else
#define USE_LFS_RAM 0 // T4.1 PSRAM (or RAM)
[B][COLOR="#FF0000"]#define USE_LFS_QSPI 0 // T4.1 QSPI[/COLOR][/B]
#endif

Audio Memory CS is 6 and looks to be found but not presented in explorer - only SDIO?:
Code:
sd_addFilesystem: 2 20003c68 nand4 1
SPIFlash Storage 3 6 nand4 16777216 8388608
> of course it is NOR - does the name matter?
SPI SD on CS of 10 also not displaying with T_4.0?

SDIO is 32GB and copy of 8,685 KB 'AUDIO...PDF' is doing WINDOWS fail beep - like when I tried before to copy to FLASH with too little room. But it seems the T_4.0 is not responsive because nothing new shows on SerMon? Same results with smaller 12KB image file.
