Hi,
I’m using the example as it is but unfortunately nothing written on SD
image, videos and audio knowing that i already make the SD FAT32
always have the below message in serial monitor:
[VID Wrn]
CH 0 MMF ENC Queue full
[VID Wrn]
CH 0 MMF ENC Queue full
.

[VID Wrn]

kindly your suport
Hi @khalil,
Can you share which example are you using and what SDK version are you using? Please share if you make any modifications to the code in the SDK version. May I also know if you are using the standard SDK or Arduino SDK?
Thank you.
Hi Kelvin
I’m using AMB82 in Arduino IDE 2.3.2, I installed Realtek Ameba boards 4.0.5
so I’m using the same example coming in Arduino without any change
Ameba Multimedia → RecodMP4 → Audio only, video only, single video with audio and double video with audio all example nothing written on SD
Dear Kelvin:
the updated SDK 4.0.5 last
regards
Hi, @khalil!
Make sure you update your board manager to get the latest version of the Arduino SDK.
The stable version is currently at 4.0.7 and the dev version is currently at 4.0.8.
Dear at_and_red:
thanks for your help,
I changed the board link to be as below:
https://github.com/ambiot/ambpro2_arduino/raw/main/Arduino_package/package_realtek_amebapro2_index.json
I install the latest SDK 4.0.7 and get the same thing, he save nothing on SD when choosing the video only example with same error as before, I’m using Samsung 64G Evo SD card
I just tested it right now with the VideoOnly.ino sketch, and it works.
Can you please dump your entire Serial Monitor output for one run here?

This is where your problem starts at:
sdio_sd_card_combine again ret = 5
try 2 times
try 2 times but fail ret = 5,please check SD card
SD_Init 1
f_mount error here, please insert SD card or use f_mkfs to format SD card to FAT32The card is inited 1
FATFS mount logical drive on sd card fail.
That says that your SD card either wasn’t found or isn’t formatted correctly.
I know you said it’s FAT32, but double check just to be sure. Check that there’s nothing in the slot that might be blocking pins, and make sure that your SD card is inserted all the way (it’s a spring-loaded slot, so you should hear it click).
Dear at_and_red:
thanks for your support
its working now
formatted again as FAT32 
I have another question if you can support
is it possible to write a txt fil on SD on ABM82 mini ? how to start
Regards
Hi @khalil,
You can refer to this guide to write text file onto the SD card in AMB82-Mini.
File System – Simple applications with SD card – Realtek IoT/Wi-Fi MCU Solutions
Thank you.
Hi Kelvin:
thanks 
I need to do like attendance system, make a text file include
the persons login and logout and send an email to microsoft 365
Another support request:
Thank you
Hi @khalil,
For the first one, you do not need to connect an external RTC if you are able to connect the AMB82-Mini to the internet using WiFi. You can take a look at our NTPClient example (NTP – Retrieve Universal Time (UTC) by NTPClient library – Realtek IoT/Wi-Fi MCU Solutions)
For the second question, you probably need to use some SMTP library to set up the sending of email. Right now, the Arduino SDK do not have this example yet. You can raise a feature request at our Arduino github repo (Issues · ambiot/ambpro2_arduino · GitHub), we will review if it is feasible to make such a feature.
Thank you.
Hi Kelvin:
thanks for your support
I will check
Thank you
