mrw/mrh/mrb 分别是 memory read word/halfword/byte,读取 memory。 mmw 则是 memory modify word,修改 memory。 3)参考链接: 代码:https://gitee.com/luyaocf/openocd.git 官方文档:https://openocd.org/doc-release/html/1 swj_newdap1)完整的 swj_newdap 命令如下: swj...
For maximum performance the driver accesses memory-mapped GPIO peripheral registers directly. The memory mapping requires read and write permission to kernel memory; if /dev/gpiomem exists it will be used, otherwise /dev/mem will be used. The driver restores the GPIO state on exit. All four G...
同时我们也会这里通过 ROM_QSPI_Init() 对 QSPI 进行初始化(实际好像可以省略)、ROM_QSPI_ReadID() 读取芯片的 ID。 2)调用 ROM_QSPI_ReadID() 的代码如下: static const uint8_t air105_read_id_code[] = { /* the address of ROM_QSPI_ReadID() API @ 0x8014 */ 0x4f, 0xf4, 0x00, 0x...
