Field Documentation

◆ chipid

uint32_t lpc2900_flash_bank::chipid

Holds the value read from CHIPID register.

The driver will not load if the chipid doesn't match the expected value of 0x209CE02B of the LPC2900 family. A probe will only be done if the chipid does not yet contain the expected value.

◆ clk_sys_fmc

uint32_t lpc2900_flash_bank::clk_sys_fmc

System clock frequency.

Holds the clock frequency in Hz, as passed by the configuration file to the flash bank command.

◆ is_probed

bool lpc2900_flash_bank::is_probed

This flag is set when the device has been successfully probed.

◆ max_ram_block

uint32_t lpc2900_flash_bank::max_ram_block

Maximum contiguous block of internal SRAM (bytes).

Autodetected by the driver. Not the total amount of SRAM, only the largest contiguous block!

◆ risky

uint32_t lpc2900_flash_bank::risky

Flag to indicate that dangerous operations are possible.

This flag can be set by passing the correct password to the lpc2900 password command. If set, other dangerous commands, which operate on the index sector, can be executed.

◆ target_name

char* lpc2900_flash_bank::target_name

String holding device name.

This string is set by the probe function to the type number of the device. It takes the form "LPC29xx".
