I bought the two units from Amazon Seesii USA with 2 day shipping on the last one. Both units were labeled with 50 KHz starting frequency. But they can start at 10 KHz if that is entered under

DiSlord And with 0.9.2 firmware I get this : ch>? SD_SendCmd err CMD0, 0xFF, 0x00000000 ?CMD0 Ok ?CMD8 Ok ?CMD8 0xAA010000 CMD8 Ok, ACMD41 99 ?CMD58 OCR = 0x0080FFC0 CardType 12 filename

No for H need compile its own firmware, it have about 14kB free flash. Only Fat32 and short filenames need ~10kB (but i don`t test this for H firmware) Also H version not have SD slot on PCB board,

DiSlord, With your comment below, do you mean that the non-ExFat version of your firmware that supports the SD cards should work on an H if I add an SD slot? ...Larry

DiSlord, With this firmware I see : ?CMD0 Ok ?CMD8 Ok ?CMD8 0xAA010000 CMD8 Ok, ACMD41 99 ?CMD58 OCR = 0x0080FFC0 CardType 12 filename VNA_20200525_04212.bmp open 0 close 0 ?Read? speed = 238139

Add support ExFAT filesystem and check work on my SD card All worked, support ExFat need additional 4kB flash and can`t be suppoted on NanoVNA-H (if add card slot in it) But on H4 stiil more flash

Hi DiSlord, It's working now , see screenshot attached (after 2 port calibration). This is shown in Tera Term : ?CMD0 Ok ?CMD8 Ok ?CMD8 0xAA010000 ?CMD8 Ok, run ACMD41 ?ACMD41 99 ?ACMD41

Thanks for made test (i don`t found old SD cards at home for check it) As i see all SD card types work Read/Write speed not big, but this limits of SD card SPI bus mode and processor. In future i try

Thank you very much, it works now.

Found my error in card type detect try this

Yes, but you card answer CMD58 CCR = 0x0080FF80 Not set Card Capacity Status (CCS) bit Need read datasheet

It still doesn't work, SDHC card uses block as read/write unit and small capacity SD card uses byte as read/write unit, is there no driver for small capacity SD card?

Yes possible old cards can`t work on high SPI speed like 36MHz I try set 18MHz speed for work, this little slowdown write from 150kB/s to 140kB/s Also, i found RTC clock (internal timer) run to fast,

Hello DiSlord, I installed a microSD card slot and tested that both 8GB and 32GB microSDHC cards can work normally, but I found an ancient 1GB microSD card that does not work. The following is the
