Hello All, Can you suggest a _good_ realization of the embedded FAT16 _and_ FAT32 filesystem driver in C or C++? It is intended mainly for the flash memory cards. The preference is maximum performance, portability, flexible configuration, static memory allocation and full compatibility to the MS spec. Intelligent caching of FAT would be the strong plus. I came through several realiza...

Hi All, I need a SD memory card controller chip, I also need to porting some MCU code, and need UART interface, low speed as 9.6K is enough. Best regards, Boki.

Hi all, I have an embedded system which is required to have memory partitioning due to safety reasons. Unfortunately there are sporadically bus address error exceptions. I am using a Motorola M68376 as a foreground/background system but I think it's no problem of the microprocessor. There are three asynchronous interrupt sources. Each of them has a different ISR assigned. The principle st...

Hi, I regularly have to sort through a fair number of memory modules (DIMMs, SO-DIMMs, etc.). All (?) of these have serial ROMs that indicate applicable parameters for the module. Most are cryptically marked -- at best. And, reading part numbers off components is tedious (easier to just discard the little beasts!) Is it possible to design a little to query these devices

Hello everyone, I'm very new to embedded systems, and debugging them. Im teaching myself and learning a lot on the way. I'm having some trouble with the wiggler, and macraigor has been less than helpful (dont blame them, I bought mine secondhand so they dont have much incentive). I can use the OCD Commander software just fine, but I'd like a way to download larger portions of memory ...

Hi I was wondering if anyone can tell me if using edk, is it possible to create 2 separate peripherals with external ports that can communicate with each other? What i'm trying to design is a peripheral which acts as a pipeline stage which has some memory that is written via a microblaze. This memory is then used to store coefficients to be used during normal pipeline operation. Mu...

Hi all, I am having trouble understanding why my C++ application is misbehaving. Object member data is allocated in stack memory, but in some cases this memory gets overwritten by other (unrelated) function calls. This seems to occur regardless of how much space I allocate for the stack. I stumbled on the variable that is being overwritten by accident. Any ideas on how I should go ab...

Hi everyone, is there a way to specify either in assembler or C where a global variable should be located in the memory? (it's an ADSP21020). The reason for this is that, in the system I'm using, the protected area of the flash contains the runtime header which reference to a symbol called ___lib_int_table (where the address for interrupt service routines will be placed). This symbol was...

Hello, I'm loooking for any statically linked memory analisys libraries, which is able to track executions of the malloc family functions. It is very important that library should be independent of the operating system. Valgrind will be perfect, but unfortunately it is strongly connected with used OS. I will be thankful for any hints, -- Piotr Piwko http://embedded-engineering.pl...

Hi, I'm stuck with a nasty problem. I'm running an 4.4.13 based kernel with a busybox on an ARM-system but it seems to leak memory... during the working hours. I know it is not the best way to do but I've monitoring the MemFree value from /proc/meminfo and I'm losing 2M/hour. It's not that big but having 100M memory free makes it crash after two days. Or at least what I think makes it...

From the Freescale WEB documentation: "If you find yourself needing a little more memory than what the 56F8365 has to offer, or simply need to interface to other devices in your system a parallel fashion, then the 56F8366 is the device for you.

We're having trouble hunting down sources for the particular flash/sram parts we need. Rather than providing a full spec of the parts needed (and expect someone here to find a perfect match :p), I was wondering if anyone knows of any other semiconductor companies not on my list that are manufacturers of memory [of any sort] and I'll go check them out. AKM, Alliance, Atmel (Temic), Aved, B...

I'm shaking the box, trying to get the software to settle enough to fit into a 64kB memory space. This is made difficult by the fact that it's a human-interface rich environment with a bit of extra fat contributed by the fact that I'm writing in C++. This is for an application that worked just peachy-keen on a captive vendor's tool set, but which is too big using gnu tools. It's to be...

I need to upgrade the cpu in a system to get more memory, speed and any other features that might be availble. The replacement cpu needs to be pin compatible with the 80c51fa. I'm leaning toward the Dallas 89c450. It has 64k of internal flash code memory, 1k of extra RAM, and runs at 1 cycle per instruction (x12). The crystal that I'm currently running is only 11 mhz. Would that be the best ...
