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.

/* The imxrt162-evk has 8MiB of QSPI FLASH beginning at address,
|
|
* 0x0060:0000, Upto 512Kb of DTCM RAM beginning at 0x2000:0000, and 1MiB OCRAM
|
|
* beginning at 0x2020:0000. Neither DTCM or SDRAM are used in this
|
|
* configuration.
|
|
*
|
|
* The default flexram setting on the iMXRT 1062 is
|
|
* 256Kib to OCRRAM, 128Kib ITCM and 128Kib DTCM.
|
|
* This can be changed by using a dcd by minipulating
|
|
* IOMUX GPR16 and GPR17.
|
|
* The configuration we will use is 384Kib to OCRRAM, 0Kib ITCM and
|
|
* 128Kib DTCM.
|
|
*
|
|
* This is the OCRAM inker script.
|
|
* The NXP ROM bootloader will move the FLASH image to OCRAM.
|
|
* We must reserve 32K for the bootloader' OCRAM usage from the OCRAM Size
|
|
* and an additinal 8K for the ivt_s which is IVT_SIZE(8K) This 40K can be
|
|
* reused once the application is running.
|
|
*
|
|
* 0x2020:A000 to 0x202d:ffff - The application Image's vector table
|
|
* 0x2020:8000 to 0x2020:A000 - IVT
|
|
* 0x2020:0000 to 0x2020:7fff - NXP ROM bootloader.
|
|
*
|
|
* We artificially split the FLASH to allow locating sections that we do not
|
|
* want loaded inoto OCRAM. This is to save on OCRAM where the speen of the
|
|
* code does not matter.
