(1) imx-itcm-unsigned.bd的內容如下，我需要知道裡面幾個參數分別的用法，分別代表什麼以及設定的規則 ? (flags/ startAddress/ ivtOffset/ initialLoadSize/ entryPointAddress)
options {
flags = 0x00;
# Note: This is an example address, it can be any non-zero address in ITCM region
startAddress = 0x400;
ivtOffset = 0x1000;
initialLoadSize = 0x1000;
# Note: This is required if the default entrypoint is not the Reset_Handler
# Please set the entryPointAddress to the base address of vector table
entryPointAddress = 0xA000;
}
(2) program_flexspinor_image_qspinor.bd 我修改過的內容如下erase 0x60000000..0x60040000，這是根據目前的code size先調大到256kBytes的flash空間，我需要知道裡面幾個參數分別的用法，分別代表什麼以及設定的規則 ? (kAbsAddr_Start / kAbsAddr_Ivt / kAbsAddr_App)
constants {
kAbsAddr_Start= 0x60000000;
kAbsAddr_Ivt = 0x60001000;
kAbsAddr_App = 0x60002000;
}
# The section block specifies the sequence of boot commands to be written to the SB file
section (0) {
#1. Prepare Flash option
load 0xc0000007 > 0x2000;
# Configure QSPI NOR FLASH using option a address 0x2000
enable flexspinor 0x2000;
#2 Erase flash as needed.(Here only 256KBytes are erased, need to be adjusted to the actual size based on users' application)
#0x40000 = 256kBytes
erase 0x60000000..0x60040000;
#3. Program config block
# 0xf000000f is the tag to notify Flashloader to program FlexSPI NOR config block to the start of device
load 0xf000000f > 0x3000;
# Notify Flashloader to response the option at address 0x3000
enable flexspinor 0x3000;
#5. Program image
load myBinFile > kAbsAddr_Ivt;
}
