Hi,
I am trying to flash 2 .elf files to S32K116 using pegdb console, bootloader.elf and app.elf.
Here are the steps I am following:
Start the gdb server with command "pegdbserver_console.exe -startserver -device=NXP_S32K1xx_S32K116F128M4"
Then using the arm-none-eabi-gdb.exe, I connect to S32K116 and try to flash .elf files with command "arm-none-eabi-gdb.exe --command=load_sw.txt"
Content of load_sw.txt is:
set style enabled off
file bootloader.elf
target remote localhost:7224
set pagination off
echo \n \t [OK] STEP-1 : CONNECTED TO DEVICE \n
load bootloader.elf
echo \n \t [OK] STEP-2 : FLASHED BOOTLOADER \n
load app.elf
echo \n \t [OK] STEP-3 : FLASHED APPLICATION \n
continue
quit
When the command are executed I can only see application running since bootloader does not prints its logs. My guess is I am missing something so the app.elf overrides the memory region. You can see the memory regions defined in .ld files
applications memory areas :
MEMORY
{
/* Flash */
m_interrupts (RX) : ORIGIN = 0x0000C000, LENGTH = 0x000000C0
m_flash_config (RX) : ORIGIN = 0x0000C200, LENGTH = 0x00000010
m_text (RX) : ORIGIN = 0x0000C210, LENGTH = 0x00013FFF
/* SRAM_L */
m_custom (RW) : ORIGIN = 0x1FFFFC00, LENGTH = 0x00000400
/* SRAM_U */
m_data (RW) : ORIGIN = 0x20000000, LENGTH = 0x000020C0
m_data_2 (RW) : ORIGIN = 0x200020C0, LENGTH = 0x00001740
}
-------
bootloaders memory areas:
MEMORY
{
/* Flash */
m_interrupts (RX) : ORIGIN = 0x00000000, LENGTH = 0x000000C0
m_flash_config (RX) : ORIGIN = 0x00000200, LENGTH = 0x00000010
m_text (RX) : ORIGIN = 0x00000210, LENGTH = 0x00000BBEF
/* SRAM_L */
m_custom (RW) : ORIGIN = 0x1FFFFC00, LENGTH = 0x00000400
/* SRAM_U */
m_data (RW) : ORIGIN = 0x20000000, LENGTH = 0x000020C0
m_data_2 (RW) : ORIGIN = 0x200020C0, LENGTH = 0x00001740
}
What could be the problem in your opinion on the issue?
Is there something I am missing to keep the first loaded .elf's memory region in the module or am I making a mistake in specifying the memory regions?
Thank you for your help and interest!
Regards,
Furkan
