When I try to set priorities in certain programs, such as init_priority(HIGH_PRIORITY), I've noticed that during linking, there's no guarantee that the programs will be compiled in the sequence I've specified based on priority. This has led to some runtime errors in my program.
I realized that in the ld file, when initializing dynamic arrays, there's no assurance of initializing init_array.* before init_array. This has resulted in runtime errors in the program. Consequently, I've rearranged the init_array.* in the ld file of NuttX to be placed before init_array and added a SORT operation to init_array.* to ensure accurate initialization based on priorities during linking.
Squashed commit of the following:
Some scripts use TABs, others spaced. Make usage consistent.
Move __exidx_end assignment inside of brackets.
Remove old __exidx_end assignment.
Move __exidx_start assignment inside of brackets.
Remove old __exidx_start assignment
Squashed commit of the following:
boards/arm/s32k1xx/s32k148evb: Correct linker scripts for the S32K148, Update README files, Hook eht S32K148EVB into the configuration and build system.
arm/s32k1xx/s32k148evb: Verify core and peripheral clocking. It is the same as the S32K146EVB. Fixed one-too-many copy-paste error in both.
boards/arm/s32k1xx/s32k148evb: Correct LED and button pin number for the S32K148EVB.
boards/arm/s32k1xx/s32k148evb: Change all occurrences of 146 to 148.
boards/arm/s32k1xx/s32k148evb: Initial S32K148EVB. Initial commit is just clone of S32K146EVB with file name changes
arch/arm/src/s32k1xx/s32k1xx_lowputc.c: Fix a typo that prevented LPUART1 from working.
arch/arm/src/s32k1xx/s32k1xx_periphclocks.c and related files: Fix yet another case of confusion between pre-decremented and non-decremented divider values. Enforce the rule that dividers are not decremented until the moment they are written into registers.
arch/arm/src/s32k1xx/s32k1xx_clockconfig.c: Fix another problem related to whether a divider is pre-decremented or not. The answer must be the divder values are never pre-decremented. They are decremented just before being written to hardware.
arch/arm/src/s32k1xx/s32k1xx_clockconfig.c: Clean up some bad conditional logic. Precedence of operators problem.
boards/arm/s32k1xx/s32k118evb: Add support for execution out of SRAM. This is helpful for bringup when you want to avoid putting a lethal image in FLASH.
arch/arm/src/s32k1xx/s32k1xx_clockconfig.h: Remove crystal frequency, it is not used.
arch/arm/src/s32k1xx/s32k1xx_wdog.h: Fix a typo in a register name.i
boards/arm/s32k1xx/s32k*evb/configs/nsh/defconfig: Create Motorola SREC output format.
