These UV ROMs might not even be available anymore because they've been discontinued, making any attempt at remediation impossible. Another problem is that embedded systems do not share a common programming language. Embedded systems usually use whatever language was convenient at the time they were created. To complicate matters even more, compilers that support extended date functions for these languages might not even be available. Of course, these concerns are all predicated on the fact that source code is available, which is not always the case.
Few applications are available for testing embedded systems.
However, this method requires custom probes for each system and can therefore be a tedious operation. Embedded systems also present problems because of the skills required to test and fix them. Although traditional systems need programmers, fixing embedded systems requires hardware engineers as well. Assessment plays a critical role in embedded-system remediation. The first step in any embedded-system project is to assess which systems are critical and analyze any problems within those systems.
