From be1d685c0d9d5535c181d0ab7220f621609abde4 Mon Sep 17 00:00:00 2001 From: Linus Nordberg Date: Thu, 23 Jan 2020 13:23:53 +0100 Subject: Revert "Add version and application info to ELF file" Adding symbols to an ELF file doesn't solve the problem we're trying to solve. We want to be able to identify which application is running on a board when we don't know what ELF file has been loaded in flash. A checksum over the contens of the flash memory seems less dumb. This reverts commit 49d39287252bf0bd2b3fd75e86d07616b56c7fd2. --- src/entropy/Makefile | 18 +----------------- 1 file changed, 1 insertion(+), 17 deletions(-) (limited to 'src/entropy') diff --git a/src/entropy/Makefile b/src/entropy/Makefile index 0285460..68723b8 100644 --- a/src/entropy/Makefile +++ b/src/entropy/Makefile @@ -1,19 +1,3 @@ -# Application number and version info are included in the ELF file -# symbol table through two global, asbolute symbols.
