Booboo explains further about booting Linux

By -

Booboo explains further, translated from the Spanish GP2x Forums (or click here for the original untranslated version) about the Linux kernel booting:

They are not hours so I will be brief:
- I have identified the majority of functions GPIO (when it has awhile I see the form to postear it everything).
- I have found out how to correctly form the SDRAM and the flash.
- I have adapted u-boot (the one that there is in the FTP of Ingenic) to the Dingoo.
- I have taken kernel linux of test. He is the one that is in the FTP of Ingenic formed for the plate TURKEY, so evidently it fails throughout, now simply is necessary to adapt it since I have done with u-boot.
By the way, which was mistaken and unlike I said previously, yes that there is to form registries of the LCD, so my more sincere excuses to those to which has confused. As you already know Ingenic does not provide drivers for LCD IL9325, so will be to currar itself it.
By the way, to that it wants to make experiments similar to which I am doing, to say to him that the FTP of Ingenic has a danger that you do not see. There are things that are in a pile of different sites, other that do not work, etc. To part of kernel of linux, most recent and trustworthy it seems to be to ucosii_0430.rar and usbboot1.4a-tools.zip. This last one is the one that in the end has served to me to find out how to initialize the SOC, since it includes besides the source code of the application (for Windows) the source code of the programitas that are loaded by USB in ram to carry out all the process of boot and engraving of the flash.
Nand-boot that there is in the FTP of Ingenic directemente does not work (it does not do __gpio_as_nand, among others things).
Here kernel starting (I insist: configuration PAVO, so it fails everything almost)

    Please, replace the word "TURKEY" to "PAVO". PAVO is a JZ4740 based laptop. Cheers, Doug.

Dingoo A380 Review

By -
Image
The nice folk at isharegifts gracefully sent me a sample Dingoo A380 for review. Having declared my pecuniary interest, in truth though, after playing with this new Dingoo, bribery and graft is strictly unnecessary for its promotion.  IMHO, the product does stand on its own merits.  It remains a testament to the original A320, and its rabid, passionate community (hey, that’s us dudes) that even in 2011, some 3 years after the word “Dingoo” became somewhat a part of the English language,  that it still remains the best Dingoo-type device.  This is because it is still the best supported, thanks to Booboo’s original Dingux, and now OpenDingux.  Dingux means access to emulators and software other than those that came with the original A320’s native uCos firmware.  Dingux allows for ports of games like Doom and Duke Nukem.  Dingux is what turned the A320 from a glorified media player into the device we know and love. It’s still necessary to put Dingux onto a stock standard A320 thoug

A somewhat new game for Dingux from ZX-81: Dingux-Mancala: A Mancala Game v1.1.0 for Dingoo/Dingux Hi All, Mancala is a board game familly, originated in East Africa. The word "Mancala" came from arabic word "naqalah" that means literaly "To move". Dingux-Mancala is the "Awari" variant, and even if the rule of this game is simple, the complexity can be compared to chess Game. The AI is based on the source code of H. Huseby & G.T. Lines, for their implementation of the classical Minimax algorithm. How to use it ? Everything is in the README.txt file. Sources are included, and this package is under the GNU public license, read COPYING.txt file for more information about it. How to play ?

With the release of FAT Dingux, it is now possible to install Dingux using only Windows!  As promised, here is The Complete Idiot’s Guide to Installing Dingux – Using Windoze Edition.  Grab the guide here in PDF , zipped here , or here for HTML . 18 October 2009 Update:   The above links will always contain the latest version of this guide . While the guide was written in July 2009, the technique shown in it remains the same as at the update date shown in green.  However, the guide refers to toddler’s or warped flash’s “local.zip” files, and contains links to these files, which are outdated. The links used to point to the A320 freeforums, until the dastardly Dan deleted them ! Grab the latest version of the critical local.zip file, referred to in the guide here: http://boards.dingoonity.org/index.php/topic,32.msg80.html#msg80

An interview with the creator of the Tauon PC-1, Volodymyr Mishin

By -
I'll bet you don't roll out of bed and think about making your own PC before breakfast.  Even you do, I bet you haven't actually  shipped . Here's someone who has.   I reached out to the creator of the  Tauon PC-1 , Volodymyr Mishyn who kindly took more than a little time to answer some detailed questions about the PC-1, how it came to be, the challenges of a project like this, his future plans for Tauon OS and what is clearly a very personal labour of love.   Many thanks Volodymyr.   Your  news blog  suggests 30 days to prototype, and 6 months to ship! If that is right, it is very impressive, given the technical and logistical activities that had to occur.  Is there more to this story? I was looking for available options before I started the project. I got myself a couple PI (3B, Zero) OrangePi, C-SKY. And tried to build some kind of educational PC for my kid. Unfortunately, the performance was awful, using Linux was too complicated even for me (I h

Update 4 January 2020: ================================================================== New, much friendlier GUI version released - see this post: https://dingoo-scene.blogspot.com/2020/01/gui-version-of-gadgetmisers-c64-romset.html ================================================================== Hello, friends, it's been awhile.  A happy 2020 to you all. If Santa was kind this year, he may have brought you one of these:   If Santa did, you'll have worked out by now that 64 built-in games, classics though some of them are, is simply  not enough .   Your travels may have led you to this c64 romset:  https://archive.org/details/C64Romset , which contains 17,068 games. If you pop them on a USB stick and slip it into your c64 Maxi/Mini, only the first 256 games will appear.  This is because there is a limit of 256 items per folder that can be displayed on the c64 mini/maxi loader. So you need to split the games into individual folders, each containing n

The Dingoo-Scene JXD S7800B (Rockchip 3188 SoC) Android Gaming Console Review

By -

1. Introduction      Since the introduction of the somewhat venerable Yinlips YDPG18, Android handheld gaming devices have been released pretty much continuously, by any number of Chinese manufacturers.      They’re not released with retrogaming in mind however.  Dedicated Android handhelds with physical controls for the consumption of nostalgic childhood memories are simply not in great demand in China, and accordingly, these devices have never been well supported by their makers, as far as the multitude of little tweaks and twerks that the Western retrogamer demands in the quest for ultimate emulation fidelity are concerned.  The view of China based manufacturers seems to be that the physical controls are an adjunct to the primary function of the device – hey, it’s an Android tablet, what else do you want?  Foremost among such frustrations has been OASS: “ornamental analog stick syndrome”, which sadly afflicts many of the devices released to date. What use are any physical cont

Tauon PC-1 review

You should give this a chance. It deserves one. Welcome to the Tauon PC-1. A Tauon is an incredibly  geeky sciency thing , as it happens, and has nothing to do with the  Great Eastern Philosopher . You won't find it for sale anywhere other than on Tauon's website , and on ebay so far as I can see,  and then only if you're a regular visitor of the ebay "vintage computer hardware" category.  It won't even turn up on ebay if you search for the product name: "Tauon PC1"  - you'll just stumble upon it one day, when you're looking for a replacement floppy drive, or a C64.  So, what is it? It's a computer in a dinky little case! Hardware wise, it has: Allwinner H3 Quad Core SOC [1ghz to 1.2ghz/1gb RAM/8GB internal NAND storage] SD slot USB slot,  HDMI and composite out Ethernet Wifi UART (send/receive signals through terminal commands) I2C (drivers aren't ready yet, but promised).   Inside the case - y
