Hey there! A few moths ago I got an Orange Pi 2g-IoT card and I have had some issues.
I am using a  USB/TTL converter to see the debug console. The preinstalled Android on the NAND memory seems to be working fine but I can't go on with the microSD boot.
I have tested several microSD cards class4 and class10 both with diverse capacities. Also I have flashed several OS images like Raspbian, Ubuntu Server, Debian and Armbian.
A thread  that I have found says that some issues with SD cards are caused by an unreliable power supply therefore I got a reliable one that works in 5V/2.5A.
In spite of my new power supply I am getting an incompleted boot secuency.

Below are attached the boot logs.

Class 4 - Raspbian

Class4 - Ubuntu Server

Class 10 - Any OS Image

I can't figure out which is the problem
Are there some problem with the SDcards? or with the board?

Any help is welcome.

Thank you in advance.

There are two batch production of 2G-IOT till now, the first batch production is only work with 8GB, since power setting is not enough for booting 16GB SD card. So whether you could run 16GB SD card or not up to which production products you have.

fix sd card issue
hello
try to use uboot with my fix https://github.com/DD1984/u-boot-RDA8810.git (branch boot_sd_thr_nand) binary is attached
now booting process looks like: power on -> bootRom -> uboot in nand -> uboot in sd card -> linux
the reason of issue was be that bootRom do not config VCC of sd card
on start of bootRom it was be 2.8v but after modem load it became 3.2v (linux also set vcc to 3.2v)2.8v is small for some sd cards
now uboot in nand configure VCC of sdcard and start uboot from sdcard

for write uboot to nand use my utility: https://github.com/DD1984/rda_cmd.git
steps for updating
1. set jumper to nand boot
2. hold button on board
3. connect usb cable to pc, wait 5 sec an release button
4. execute cmd on pc: sudo ./rda_cmd write bootloader u-boot.rda
5. do not change jumper - reboot board

Hi! Thank you for the utilility and the explanation.

I have had to change the device name on the code  to /dev/ttyUSB0.
I have followed the steps but fifteen seconds after that I executed the command I got this error.

# ./rda_cmd write bootloader u-boot.rda
cmd: connect(0), data rcvd error, len: 0
can't connect to device

I can see in the serial port that the card boots in the PDL loading correctly.

I don't know if I have some wrong configuration on my system or it is about the utility. Any idea?
And i neither know if the bin that you attached is for a specific card's batch. The mine one has a RDA8810PL.

Thanks!

do not change dev to ttyUSB0 - it must be ACM0
update rda_cmd from git repo and try again (rda_cmd will detect device automatically)
