Orange Pi 2G IoT Board Can Now Boot Linux from NAND Flash

Orange Pi 2G IoT is a $10 development board with a 2G cellular modem that was launched last March. The board is based on RDA Micro RDA8810PL processor designed for cheap Android phones, but Linux support was also promoted, and an RDA8810 Android SDK was released in April. It was the first time RDA8810 was used in a development board, and unsurprisingly it was, and still is, a challenge to use such board, as software support is on-going… So people who purchased the board has troubles with controlling GPIOs, or booting Linux from the SoC’s built-in NAND flash, instead reverting to booting from a micro SD card. Luckily, Orange Pi forum’s user surfero75 worked on the latter, found a solution, and posted instructions in Spanish. He wrote those instructions leveraging the work done by Aib user, and I summarized the main steps below explaining how install and boot from NAND flash (Warning: This could potentially brick your board if something …

RDA Micro RDA8810 Android SDK with Linux & U-boot Source Code for Orange Pi 2G IoT Board Released

Orange Pi 2G IoT board was released a couple of weeks ago, shortly followed by Android and Ubuntu images, but since it was not based on Allwinner, but an RDA Micro  8810PL processor, we did not have any source code so far, which can be a real problem for a development board… Shenzhen Xunlong has now managed to upload a 6.7GB Android SDK to MEGA, with the link published via Orange Pi Resources page. MEGA has a download limit which depends on how much traffic they get at the time, and after 5.3 GB download,  I was asked to register for a PRO account, or wait for four hours before resuming the download. If you want to avoid this limit for any large MEGA download, you can run megadl instead. That’s what I did in Ubuntu 16.04 (remember to escape any special characters with \): Once the download is done, none of the files have extension, but the first file …

Orange Pi 2G-IOT Board Based on RDA8810PL Cortex A5 Processor to Support Bluetooth and GSM

[Update: The board featured below was initially announced as Orange Pi Zero Plus, but considering it may have confused people as it is not at all compatible with Orange Pi Zero, it has been renamed to Orange Pi 2G-IoT] Linaro mentioned Orange Pi i96 board last fall at Linaro Connect US. It was supposed to be a $9.99 board powered by an RDA Micro Cortex A5 processor with 2Gbit RAM and 4Gbit NAND flash on-chip. There has not been any news since then, but Shenzhen Xunlong has apparently gone ahead with an RDA Micro Cortex A5 board since they’ve posted some pictures of Orange Pi Zero Plus (Note: very slow server) with an RDA Micro ARM Cortex A5 processor. Orange Pi 2G-IoT preliminary specifications: SoC – RDA Micro 8810PL ARM Cortex A5 processor @ up to 1.0 GHz with 2Gbit (256 MB) on-chip LPDDR2 RAM, 4Gbit (512 MB) on-chip SLC NAND flash , 256KB L2 cache, Vivante GC860 3D GPU, …
