nvmem_create_entry

Parameters:

ulFileId	nvmem file Id: NVMEM_AES128_KEY_FILEID: 12 NVMEM_SHARED_MEM_FILEID: 13 and fileIDs 14 and 15
ulNewLen	entry ulLength

Returns:

on success 0, error otherwise.

Create new file entry and allocate space on the NVMEM. Applies only to user files. Modify the size of file. If the entry is unallocated - allocate it to size ulNewLen (marked invalid). If it is allocated then deallocate it first. To just mark the file as invalid without resizing - set ulNewLen=0.

nvmem_get_mac_address

Parameters:

[out]

mac

mac address

Returns:

on success 0, error otherwise.

Read MAC address from EEPROM. mac address as appears over the air (OUI first)

Definition at line 197 of file nvmem.cpp.

nvmem_read

Parameters:

ulFileId	nvmem file id: NVMEM_NVS_FILEID, NVMEM_NVS_SHADOW_FILEID, NVMEM_WLAN_CONFIG_FILEID, NVMEM_WLAN_CONFIG_SHADOW_FILEID, NVMEM_WLAN_DRIVER_SP_FILEID, NVMEM_WLAN_FW_SP_FILEID, NVMEM_MAC_FILEID, NVMEM_FRONTEND_VARS_FILEID, NVMEM_IP_CONFIG_FILEID, NVMEM_IP_CONFIG_SHADOW_FILEID, NVMEM_BOOTLOADER_SP_FILEID, NVMEM_RM_FILEID, and user files 12-15.
ulLength	number of bytes to read
ulOffset	ulOffset in file from where to read
buff	output buffer pointer

Returns:

number of bytes read, otherwise error.

Reads data from the file referred by the ulFileId parameter. Reads data from file ulOffset till length. Err if the file can't be used, is invalid, or if the read is out of bounds.

Definition at line 85 of file nvmem.cpp.

nvmem_read_sp_version

Parameters:

[out]

patchVer

first number indicates package ID and the second number indicates package build number

Returns:

on success 0, error otherwise.

Read patch version. read package version (WiFi FW patch, driver-supplicant-NS patch, bootloader patch)

nvmem_set_mac_address

Parameters:

mac	mac address to be set

Returns:

on success 0, error otherwise.

Write MAC address to EEPROM. mac address as appears over the air (OUI first)

Definition at line 179 of file nvmem.cpp.

nvmem_write

Parameters:

ulFileId	nvmem file id: NVMEM_WLAN_DRIVER_SP_FILEID, NVMEM_WLAN_FW_SP_FILEID, NVMEM_MAC_FILEID, NVMEM_BOOTLOADER_SP_FILEID, and user files 12-15.
ulLength	number of bytes to write
ulEntryOffset	offset in file to start write operation from
buff	data to write

Returns:

on success 0, error otherwise.

Write data to nvmem. writes data to file referred by the ulFileId parameter. Writes data to file ulOffset till ulLength.The file id will be marked invalid till the write is done. The file entry doesn't need to be valid - only allocated.

Definition at line 137 of file nvmem.cpp.

nvmem_write_patch

Parameters:

ulFileId	nvmem file id: NVMEM_WLAN_DRIVER_SP_FILEID, NVMEM_WLAN_FW_SP_FILEID,
spLength	number of bytes to write
spData	SP data to write

Returns:

on success 0, error otherwise.

program a patch to a specific file ID. The SP data is assumed to be organized in 2-dimensional. Each line is SP_PORTION_SIZE bytes long. Actual programming is applied in SP_PORTION_SIZE bytes portions.
