In order to get enough code running to do mallocs or even use C code, you already have working memory. You need to define your problem. For example is this design verification or production testing?

Are you testing the memory chip itself or the board. And your testing is often production testing, the manufacturing solder points.

The data lines, the address lines, the control lines. The chicken and egg problem is you want to run software on the embedded processor which requires code that runs somewhere, and that implies memory could just be flash and not need any or minimal. Every address line, etc. Otherwise you need to come up with a scheme or declare chunks of memory to not be tested.

Or take a multi stage approach, the rom boot code can do a quick check of a small part of ram without using it to run. Then copy the main test program to that small chunk of ram and run within it. Then do the main memory tests with more code flexibility. Can use C instead of assembler for example.

Types of test, you need to understand the failures, you may want to test solder joints in particular and pcboard traces. So you can have open connections so you want to make each pin a one and a zero, also you can have shorts, which the one and zero covers, and you might have "friendly bits" where neighboring pins might have a short to each other so you want to have each pair of signals be different from each other.

Often folks will do tests like all ones, all zeros, 5s, As. Then checkerboard tests where one memory location has say 5s and the next has As. As a quick test I cover most of that in a couple of tests, if you use a pseudo randomizer, something repeatable like an lfsr, one pass to fill all of memory using the randomizer, re-seed, go back through and check.

Also you know and control how much of the memory. Normally I will write processor based tests in C, but wont use any C library calls like malloc or printf or anything like that.Real news, curated by real humans.

Additional use cases that you should test on iOS 1. Someone logs into your app when the Facebook app is installed and iOS Facebook integration is enabled. If someone clicks “Cancel” in response to your Facebook Login read permissions request, he / she will need to go into the iOS system settings to re-enable Login for your app.
