Netgear Mp101 Hack카테고리 없음 2020. 3. 6. 02:33
The Netgear MP101 MP3 player was brought up just before, in the circumstance of somehow unbricking one using OpenWrt. The response then has been that it could not really be produced to run OpenWrt because the manufacturing plant firmware operates eCos. It transforms out that the MP101 is usually structured on the Supply9 Marvell Libertas 88W8510H, which is definitely designed for Wi-Fi entry point duties, and is usually indeed used in some of the products detailed in the TableOfHardware. Allegedly the gadget offers 8 MB DRAM.
It has an Ethernet interface, Wi fi, line-level stereo system RCA (analog) sound results, and a headphone jack port. Unnecessary to say, with Linux/OpenWRT, it could end up being a great deal more helpful than it will be off the space. (The eCos firmware is functionally limited, buggy, and left behind by Netgear.) So my question is: would the fact that it operates eCos out of the box totally preclude it from working Linux/OpenWRT? Thanks, Robert. In case you believe no one's having to pay attention. This would be a excellent project - there are many OpenWRT individuals whose target system is definitely a music participant like the MP101!
Netgear Mp101 Hack
Nevertheless, the very first (?) hurdle can be a huge one: You've obtained to obtain at minimum a minimal version of OpenWRT on the system, so that you possess somewhere to start. That action has been thought out for Linksys, Netgear, and other techniques, but presuming you have got a 88W8510 edition of OpenWRT put together, perform you understand what it will take to load that system onto the MP101? Here's expecting that the answer is definitely 'Yes'.! I wear't understand why I didn't mention it just before, but Netgear will offer a Squat file of source program code online, per eCos'beds GPL-derived license. I poked through it and it looks like it'beds targeted for constructing specifically in a Cygwin atmosphere. Putting OpenWRT on my Motorola router will be the level of my embedded expertise; but provided the Netgear supply release will be full, I suppose it would end up being probable to glean from it how to proceed about developing a MP101-bootable picture. I find that the eCos create dependences are usually in Debian so probably I'll play with it a little more and notice if I can replicate the MP101't manufacturer firmware under Linux.

I find that the eCos build dependences are usually in Debian so maybe I'll have fun with with it a little even more and discover if I can duplicate the MP101's i9000 factory firmware under Linux. I've simply obtained an MP101, so I had a quick appearance into this. The bad news is that the Marvell nick provides no MMU, so it can't (AFAIK) run OpenWRT.
Nevertheless, that doesn't imply it can't run Linux: the ucLinux spots to the Linux kernel can get it working on a system with no MMU (with all the restrictions that implies, of training course). Is certainly a Linux distribution for a container that operates on a identical chip. Nevertheless, the firmwares from that can'capital t just become loaded directly onto the MP101 - they appear to be in a totally different structure. The WL-530G firmware appears to have got a little header, after that a decompressor for the kernel, then the kernel in gzip format. The MP101 file, on the various other hand, provides a (different) small header, beginning with the letters 'MRVL', after that after the header.
It provides a lot of data that indicates nothing at all to me. Maybe someone smart around right here may become able to provide a idea. On a more positive notice, the board appears to have a room to solder on a JTAG connection with the regular ARM pinout - this could be very helpful for trying to obtain Linux to arrive up on the container. I'd become very interested to understand whether anyone'h curious in getting Linux to function on this container, and especially if anyone provides any information that could end up being helpful. (If there are many like individuals, we should most likely take the conversation somewhere else to avoid polluting the OpenWRT community forum with information about a box that can'capital t even run it!). # jtag UrJTAG 0.10 # Copyright (G) 2002, 2003 ETC s.r.o.

It bothers me that the MP101 can be so near to perfect hardware for an web radio. I would including to know if the 88W8500-Bar processor chip could become replaced with a identical processor chip that has an MMU so it could run OpenWrt. I understand that semiconductor manufacturers frequently create what will be fundamentally the exact same product but disable certain features when they are to become offered at a lower costs.
If there is a much better processor chip that is pin-for-pin compatible, it should become worth getting the processor replaced so it could operate OpenWrt. The little flash memory space could most likely also become replaced. The press release saying the 88W8500 mentions a USB interface. Probably that functionality will be built-in and would work if one were to connect the processor chip pins. I recognize that router chip makers do not provide any details to the public about their items. (I can't even find a datasheet for the 88W8500.) Somehow the public must have acquired quite a bit of details about the 88W8500, because so very much open-source work has been carried out. Where do they get this details?
If it can be not feasible to enhance the 88W8500, the MP101 is usually pretty very much ineffective. One might be capable to toss out and substitute the routine table or eliminate the screen on the front side cell and use it. I wonder if it might end up being useful to run OpenWrt on a different router and redirect the inputs and results to the MP101 equipment through the Ethernet, port? (I put on't know enough about Linux to know if this can be a ridiculous question.) If OpenWrt on another router could do that, after that it would appear like the MP101 might be able to manage the information transfers making use of Jeremy't Liberated Libertas firmware at Bitsum.com.
