Question

我正在尝试将我的固件刷入STM32L152，但我有：

firmware.cfg

source [find interface/stlink.cfg]

set WORKAREASIZE 0x8000
transport select hla_swd

source [find target/stm32l1.cfg]

init_reset halt

program build/firmware.bin verify reset exit

有趣的是，在尝试编程firmware.elf时，一切正常。当然，firmware.bin是从firmware.elf生成的，所以它们共享相同的链接描述文件（或者这部分我错了？）：

MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 256K RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 32K } ...

我也尝试过OpenOCD 0.10.0和0.9.0。

Answer 1

从文件build / firmware.bin写入0个字节

firmware.bin丢失了它的偏移信息，因为它是原始二进制格式。您最好直接尝试刷新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：

program build/firmware.bin 0x08000000 verify reset exit

找不到地址0x00000000的闪存库
