arm - 找不到地址 0x00000000 的闪存组

Question

我正在尝试将我的固件刷写到 STM32L152 中，但我有:

固件.cfg

source [find interface/stlink.cfg]set WORKAREASIZE 0x8000transport select hla_swdsource [find target/stm32l1.cfg]init_reset haltprogram build/firmware.bin verify reset exit

有趣的是，当尝试对 firmware.elf 进行编程时，一切正常。当然，firmware.bin 是从firmware.elf 生成的，因此它们共享相同的链接器脚本(或者我在这部分有误？):


内存
{
闪存 (rx):原点 = 0x08000000，长度 = 256K
RAM (xrw):原点 = 0x20000000，长度 = 32K
}
...


我也尝试过 OpenOCD 0.10.0 和 0.9.0。

Answer 1

wrote 0 bytes from file build/firmware.bin

firmware.bin 丢失了偏移量信息，因为它是原始二进制格式。您最好尝试直接刷新 firmware.elf 文件。

或者，您可以尝试将正确的闪存偏移量放入 OpenOCD 命令中:

program build/firmware.bin 0x08000000 verify reset exit
