Automatically copy RAM_VECTORS when using ARMClang and IAR

by Bohdan.Hunko＠infineon.com

Hi, When poking around some startup files I have found interesting place related to RAM_VECTORS support CMSIS have __PROGRAM_START macro which is different for each compiler. For GCC it uses __cmsis_start, for ARMClang - __main and for IAR - __iar_program_start Basically each of the functions should copy several sections (.TFM_DATA for example) from FLASH to RAM and zero out some parts of RAM (for .TFM_BSS for example) In current implementation GCC __cmsis_start function also copies the vector table from FLASH to SRAM (if RAM_VECTORS are enabled) But ARMClang and IAR equivalents of that function (__main, __iar_program_start) does not seem to take care of copying vector table, so platforms startup should do that I wonder if there is a way to change linker script in a way which will make copying of vector table automatic (by compiler dependent function). This will make platform startups a bit cleaner and will allow platform to just use __PROGRAM_START macro without any additional code to copy vector table. From what I see IAR has "initialize by copy" syntaxis so I think it may be used to tell IAR to automatically copy vector table. It is a bit more tricky with ARMClang as I have not found a way to do that there. I am not a big expert in ARMClang and IAR so maybe someone may help me here, give some directions or confirm that currently there is no way to make this idea work. Basically the intention is to simplify platform startup code and offload common operations to compiler specific platform independent functions.

Library fetching improvements

by Bohdan.Hunko＠infineon.com

Hi, Recently I have been adding some new libraries to my TFM project and what I always end up doing is: go to some existing file which fetches the library, copy code from there, paste it to my file, change few links, versions and names. It is a bit annoying to copy-paste that code each time, also it is hard to maintain (if pattern for fetching libraries changes) and also copy pasting might lead to some code not being updated. My proposal is to have a function that can be used to fetch a library. This way it will be easier to add new libraries and this change will make code cleaner. Please let me know your thoughts on this proposal.

by Doka.Dokanov-Dobrovolskyi＠infineon.com

Hello! My name is Oleg. I'm working on TF-M Isolation Level 3 testing and I need to develop test cases list for it. Could you be so kind to provide me the test cases list? May be you know where I can find it by myself? Also I have test cases list for Isolation Leve 2. Am I right that it can be reused for Isolation Level 3 with some changes? I will be very appreciate for any help. Thank you so much, Oleg Dokanov
