examples/peripherals/usb/host/msc, msc_host_vfs_register ESP_ERR_NO_MEM (IEC-358)

[savenlid]

Answers checklist.

• I have read the component documentation ESP-IDF Components and the issue is not addressed there.
• I am using target and esp-idf version as defined in component's idf_component.yml
• I have searched the issue tracker for a similar issue and not found any related issue.

Which component are you using? If you choose Other, provide details in More Information.

device/esp_tinyusb

ESP-IDF version.

5.5

Development Kit.

esp-p4 homemade with wusb3801 cc-chip and a lot more

Used Component version.

1.1.3 latest

More Information.

I can attach a usb-memory stick once.
2nd time it refuses
msc_host_vfs_register

I did follow the example code very strictly ( not exactly due to being in a bigger system of code =
But to in all essential part, I think its identical.

I run on a p4 and it has some special config files, but there is no comments in read.me about them or if they are a must etc.
I did not include any of the configs from example.

I am not on a hub.
My CONFIG_FATFS_VOLUME_COUNT is 2
I did an APP_QUIT, and tore everything down ( via console command ) it does not help.

From console i did read out heap after vfs_mount refused due to no_mem

heap
min heap size: 312888
this is a P4 with 32MB ram

tasks shows no problem with stack-water-mark from
console task-dump

Hi @savenlid! Please be aware that the following suggestions are generated by a bot and haven't been fact-checked by Espressif Systems. We hope that this message will help you until an Espressif Engineer looks at your issue.

Thank you for the detailed report. Based on the information provided and the available Espressif documentation, here are some key points and suggestions regarding your issue with msc_host_vfs_register returning ESP_ERR_NO_MEM on the second USB stick insertion in the ESP-IDF examples/peripherals/usb/host/msc example:

---

Key Observations

• You can mount a USB stick once, but the second attempt fails with ESP_ERR_NO_MEM.
• You have plenty of free heap (min heap size: 312888) and no stack issues.
• You are using ESP32-P4, ESP-IDF v5.5, and usb_host_msc v1.1.3.
• You are not using a USB hub, and CONFIG_FATFS_VOLUME_COUNT is set to 2.
• You are tearing down the stack with an APP_QUIT and reinitializing, but the issue persists.

---

Analysis from Documentation

1. Proper Stack Deinitialization is Critical
   The usb_host_msc documentation and the example README both emphasize that to cleanly reinitialize the USB Host stack, all resources must be deinitialized in the correct order. If any part of the stack (MSC device, VFS, or USB Host library) is not fully deinitialized, memory may not be released, leading to ESP_ERR_NO_MEM on subsequent attempts.

2. Deinitialization Sequence
   The correct order is:

   • Unregister the VFS (usb_msc_vfs_unregister)
   • Uninstall the MSC device (usb_msc_uninstall_device)
   • Uninstall the MSC driver (usb_msc_uninstall)
   • Uninstall the USB Host library (usb_host_uninstall)

   If any of these steps are skipped or fail, memory may not be freed, causing the next msc_host_vfs_register to fail with ESP_ERR_NO_MEM even if the heap appears sufficient.

3. Known Issues and Limitations

   • The MSC driver only supports devices using the BOT protocol and Transparent SCSI command set.
   • The number of simultaneously mounted devices is limited by CONFIG_FATFS_VOLUME_COUNT, but you have this set to 2, which should be sufficient for your use case.
   • The example notes that the stack can be deinitialized by shorting GPIO0 to GND, which triggers a full teardown. If you are not following this exact method, ensure your teardown sequence matches the example.

4. No Special P4 Configs Required
   There is no mention in the documentation or example README of special configuration files required for ESP32-P4 beyond standard menuconfig settings. However, endpoint and memory constraints must be considered if you increase the number of devices.

---

Recommendations

• Double-check your teardown sequence:
  Ensure you are calling all deinitialization functions in the correct order, as described above. Missing any step can leave resources allocated.

• Monitor Return Values:
  Check the return values of each deinitialization function to ensure they succeed before proceeding to the next step.

• Compare with Example:
  If possible, try running the official msc_host_example with minimal modifications on your hardware to see if the issue persists. This can help isolate whether the problem is in your integration or a more general issue.

• Heap Fragmentation:
  Even with a large minimum heap, fragmentation can prevent large contiguous allocations. Try resetting the board between tests to see if the issue is related to heap fragmentation over time.

---

Documentation References

• USB Host MSC Driver Usage & Deinitialization
• MSC Host Example & Limitations

---

If after following these steps the issue persists, please provide the exact teardown code sequence you are using, and any error codes returned by the deinitialization functions. This will help further diagnose whether the issue is with resource cleanup or something else.

Let me know if you need more specific code examples or further assistance!

Hi @savenlid

I see you are using a custom board, is the unchanged msc host example working correctly on your setup? Especially the part, where you are seeing an error, during re-attaching an USB device for the second time.

[savenlid]

Unchanged works.

I started slowly to merge my things into your "clean" example code/project.

Just a few things merged in and it fails.

NVS, custom partitions for 16MB flash and some littlefs partitions.
start the network.
Add GPIO to enable VUSB, since i have VUSB not hard-wired.

it fails on second connect of usb-memory-stick.
I (15575) example: MSC device connected (usb_addr=1)
E (15575) MSC VFS: msc_host_vfs_register(92):
E (15575) example: msc_host_vfs_register failed: ESP_ERR_NO_MEM

Hi @savenlid I tired running the code you provided on esp32p4 ev board, below are build and error logs. I used IDF 5.5 and IDF 6.0. Both the same.

Rebooting...

esp keeps restarting and I don't event get to see the
E (15575) example: msc_host_vfs_register failed: ESP_ERR_NO_MEM

[savenlid]

I will fix and comeback.

I had data in my flash ( certain partitions) already from a previous flashing.
I will try to workaround this dependency.

[savenlid]

Hi, @peter-marcisovsky
thanks for looking into this.

#1, changed ESP_ERROR_CHECK to ESP_ERROR_CHECK_WITHOUT_ABORT when mounting non existing partitions
#2, one of the partitions needed to contain data (for example to not work), so I put that in for the modified example.

I tried to modify your example as little as possible, the actual example code is untouched.

Please try this V2
https://drive.google.com/file/d/1L9X4r6NlkVJzhN71brHq2VbDDyWg7NWK/view?usp=drive_link

seems the littlefs VFS and the USB VFS interfere ?
just speculating.

I will retry.
I thought I had checked it could build clean.
But obviously not.

@peter-marcisovsky

my example has 16MB and custom partition table.
Not sure what happened to that.
But I have seen full-clean wipe menuconfig-settings sometime.
Compiled and ran at my site.

In the link with the zipped msc2.7z its correct when I open menuconfig.
Custom partitions and 16MB.
Possibly even some other settings I don't remember, but I tried to adjust just the minimal possible.

Thanks
