File manager for SD card (SCPI only)

[prasimix]

Add functionality to list, delete, modify, copy files stored on the SD card. The following type of files should be stored on the SD card:

• Copies of user profiles that resides on the EEPROM
• Values for programming voltage, current and duration of the LIST
• Data logging files

MMEMory SCPI subsystem will be used for remotely managing SD card files. Additionally, bidirectional file transfer (DOWNload, UPLoad?) between PSU and host computer has to be added.

At *RST, this value is not set to the root path.

Version 1.1 SD Card Failed on startup, but seems to respond to firmware anyway. See SCPI commands below:

*IDN? Envox,EEZ H24005 (Due),CS17054,v1.1

MMEM:CAT? "System Volume Information,FOLD,0"

MMEM:INFO? 12288,7974543360

*TST? 1

DIAG:INFO:TEST? "1, EEPROM, installed, passed","0, SD card, installed, failed","1, Ethernet, installed, passed","1, RTC, installed, passed","1, DateTime, installed, passed","2, BP option, installed, skipped","1, Fan, installed, passed","1, AUX temp, installed, passed","1, CH1 temp, installed, passed","1, CH2 temp, installed, passed","1, CH1 IOEXP, installed, passed","1, CH1 DAC, installed, passed","1, CH1 ADC, installed, passed","1, CH2 IOEXP, installed, passed","1, CH2 DAC, installed, passed","1, CH2 ADC, installed, passed"

Still had SD Card Fail on Power off/Power on/ Hard Reset, with a single high pitch beep - need to press home to continue.

If I move the lines

if OPTION_SD_CARD

sd_card::init();

endif

down below

if EEZ_PSU_SELECTED_REVISION == EEZ_PSU_REVISION_R3B4 || EEZ_PSU_SELECTED_REVISION == EEZ_PSU_REVISION_R5B12

fan::init();

endif

and recompiled, and that seems to avoid the error. Not sure if you needed the SD card earlier, but that was my observation. May be timing related.

After this, however, the MMEM:CAT? caused the unit to lock up.

Do you have this problem only on the latest version? We moved recently to a different SD library.

[Helix70]

Correct. No SD Card errors until 1.1 with the new SD card library.

[TimWoodburn]

I've just updated to v1.1 and also have "SD Card Failed" message on start.

CPU R5B12, Arduino IDE 1.8.5 SD version 1.1.1 Used SDFAT from EEZ GIT

Fault was not apparent on V1.0

If I follow Helix70s steps I get the following: ERROR: -250, "Mass storage error" ERROR: -350, "Queue overflow"

test? shows "SD card, installed, failed"

Any ideas?

[mvladic]

Please, upload latest firmware (we just committed some changes) and execute debug? SCPI command and let me know what you get. Thanks!

Hi,

Hm, strange. "card begin result" and "fs begin result" is 1, which is good and you shouldn't get "SD card, installed, failed".

[TimWoodburn]

This unit was only assembled a couple of weeks ago however I don't recall noticing the SD card error with v1.0.

I pushed the SD card and rebooted...failed on start. Rebooted again, fault no longer apparent. I've recycled the power a few times and mostly no failures.

Perhaps the card wasn't fully located...seems odd though that the fault wasn't apparent on V1.0.

Thanks for having a look.

[mvladic]

Would you be so kind and next time when you get SD failure, execute "debug?" and send me (we should see "SD card begin result error: ???" line with SdFat library internal error code).

[TimWoodburn]

The PSU reported an SD card failure in self test on 4 of 20 power-ups from standby. The output of debug after failure is as follows:

SD volume is FAT 0 SD card begin result: 1 SD fs begin result: 0 SD blocks per cluster: 0 SD cluster count: -1 SD fat start block: 0 SD fat count: 2 SD blocks per fat: 0 SD root dir start: 0 SD data start block: 0 SD card size: 7990 MB SD flash erase size: 128 blocks SD erase single block

[mvladic]

Because of:

SD fs begin result: 0

I know that filesystem initialization is failing. But, I need more info.

Please try the same thing with the latest psu-firmware and SdFat library.

Hopefully we will se after SD fs begin result: 0 one more line with additional info. Thanks!

[Helix70]

I updated and tried the master firmware. It seems ok. Now I get this from debug?

I'm more interested in debug info when SD card initialization fails ;)
