I normally don't use dynamic allocation in embedded projects, however there are situations where this isn't possible. I'm working on a project with LPC1768 Cortex-M3 MCU that features 32kB+32kB RAM. I'm using lwip+mbedTLS to make a TLS connection to AWS IoT Core through Ethernet. After a precise allocation of data blocks (incoming Ethernet packets, outgoing packets and so on), it see...

We use the Hitachi H8S2676 chip in one of our products and a while ago Renesas told us the chip was going out of production. Someone here forgot to do a lifetime buy from them in time but we recently did a lifetime buy of several thousand from a third party company. In the first production run of over 100 boards, every single one failed the manufacturing test. It seems at least o

I'm working with a very old 68360 based embedded system running from flash ROM based on pSOS+ RTOS, and need to debug. The BDM cannot do hardware breakpoints while running from ROM and thus I'm looking for an emulator that may work with this. I've tried an old Mikrotek power-pack, but it's DOA upon boot, and am looking at what anyone may have around they no longer need. I don't have a bud...
