Also I have set the parameter to 8 instead of 4 by default because there were many "alloc failed" messages in debug log even during initialization / automatic IP address assignment via DHCP negotiation.

By default, firmware and CLM files are provided in memory.
|
|
This selection enables an option to load the firmware and CLM
|
|
files from a mounted file system.
|
|
|
|
A snapshot of file for the BCM43362 are available in the tools
|
|
repository: https://bitbucket.org/nuttx/tools/src/master/bcm43438/
|
|
|
|
The latest files from Cypress are available in the Linux kernel:
|
|
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/brcm
|
|
The 43438 is a variant of the 43430 and will even identify itself as
|
|
such. The calibration file used in the past is called:
|
|
brcmfmac43430-sdio.AP6212.txt. The firmware is brcmfmac43430-sdio.bin
|
|
|
|
If not defined, then your board support logic will have to
|
|
to provide the firmware files (and CLM files for the CBM43438)
|
|
in board/src directory. For the BCM43362, the following would
|
|
need to be provided:
|
|
|
|
const uint8_t bcm43362_firmware_image[];
|
|
const unsigned int bcm43362_firmware_image_len;
|
|
|
|
For the BCM43438, the following would need to be provided.
|
|
|
|
const uint8_t ap6212_firmware_image[];
|
|
const unsigned int ap6212_firmware_len;
|
|
|
|
const uint8_t ap6212_clm_blob[];
|
|
const unsigned int ap6212_clm_blob_len;
|
|
|
|
NVRAM files are currently only supported from memory. The following
|
|
must be provided all configurations. For the BCM43362:
|
|
|
|
const char bcm43362_nvram_image[];
|
|
const unsigned int bcm43362_nvram_image_len;
|
|
|
|
And for the BCM43438:
|
|
|
|
const char ap6212_nvram_image[];
|
|
const unsigned int ap6212_nvram_image_len;
|
