I've just been trying to use avra, but it outputs coff or something, so obdump has trouble disassembling it. I am also not sure how to link the result(ihex have no symbol info). So now I believe the thing is next to unusable. Someone correct me if I am wrong, plz. Are there any other, usable alternatives to Gas that have usable macro constructs (+labels)?

While those who make heavy use of floating-point computations in embedded sytems probably go for systems with hardware support for floating-point calculations, there are plenty of systems without such support out there. And the existence of soft float implementations indicates that there is a real need for doing floating-point computations on systems without hardware floating-point support. ...

Asymmetric multiprocessing (AMP) systems fulfill the need for high performances and real-time by combining the responsiveness of a MCU (Cortex-M) with the processing power of an application processor which runs a full OS. This webinar presents a technical overview on asymmetric multiprocessing and its implementation on an NXP i.MX 7 Colibri System on Module running Android on the MPU (Cortex-A,...

What are folks using for reliable file system on for example SST26VF064B 64Mbit SQI flash? Naive FAT will quickly wear out device for some uses; needs a wear-leveling file system. Needs to be power-off safe as well; no corrupted file system from arbitrarily-timed power cut. Anybody? Thanks, Best Regards, Dave PS: A customer of ours used TINY by HCC some years back. It is unfortunately ...

It has been a while since I looked at anything Cypress. I have a couple of PSOC something sticks that were fun to play with a bit, but I never used the CPU for a project. Now they have come out with a PSOC 6 with asymmetric dual processors, and M4 and a M0+ with an optional BLE radio and stack. Looks like they are using the M0+ to control the BLE and the M4 is for user code. I t

I'm trying to put all ISRs in RAM[*]. Unfortunately, depending on the code, arm-gcc could call some system functions that are located in Flash. For example, if I use a switch statement, the compiler calls a piece of code of system libraries (that are in Flash) that use a table lookup to manage the switch. Is it possible to force arm-gcc to avoid calling system functions from ISRs, so...

I'm designing a electronic device running an embedded HTTP server. I'm using lwip TCP/IP stack and the httpd application that comes with lwip. Because the device is under an ADSL router and the public IP is dynamic, I need to register to a DDNS service, configure it in the router and open one port (NAT). These steps are too tricky for the most of my users. So I'm thinking to a simpler so...

I'm not an expert on test-driven development. I know the general ideas behind TDD, however I never used it in my projects. I want to start using TDD, at least creating some unit testing on some more critical units. However I have many difficulties. For a module that calculates a checksum, it is very simple to create a unit test. However an embedded firmware is more complex. Consider...

Hi there, I am trying to implement a CAN sniffer on an Altera DE2-115 evaluation board with the Terrasic AD/DA data conversion card (High Speed Mezzanine Card (HSMC) via SMA. I am using two A/D channels for CAN_H and CAN_L bus signals. Before testing it with real CAN signals I want to make sure that the connection is right in terms of voltage swing, differential termination and peak
