HI bleow is the my platform :

- ubuntu linux with arm platform

Please help me on this any body .
My BT/WIFI chip : 88w8997 (marvell chip) .
WIFI : mwifi_sdio (1.0 version )
BT : hci_uart (2.3 version)

NOTE : Wifi is working but getting issues in BT
Thanks,
Naresh

[vinothkumars]

Check with some other hardware also.

[naresh_nakka]

Hi vinothkumars,
Its wireless chipset (WIFI +BT combo )

• WIFI is working (wifi firmware able to download )  but why not BT firmware is not able to download .
• Do you suspecting Hardware issue ?
• just for your information : 
  WIFI firmware name: sdsd8997_combo_v4.bin
  BT firmware name : helper_uart_3000000.bin
  
  Thanks,
  Naresh

[vinothkumars]

BT using uart or sdio connection.

for uart you have to use one sduart firmware

[naresh_nakka]

Hi ,

Even i placed sduart firmware inside mrvl folder .

still it looking for helper firmware and loading is failed to download .

Thanks,

Naresh

[naresh_nakka]

Hi ,

Acutally for our chipset we are using 

BT  -> uart interface 

WIFI  ->  sdio interface .

But bluetooth driver looking for "helper_uart_3000000.bin" firmware .

please help me on this .

Thanks,

Naresh

[vinothkumars]

Hi,

Basically, this BT is uart connection, so you have to this firmware,

Please find the location -

https://github.com/NXP/imx-firmware/blob/lf-5.10.52_2.1.0/nxp/FwImage_8997_SD/sdiouart8997_combo_v4....

[naresh_nakka]

Hi , 

Still it looking for helper firmware even i placed the sdiouart firmware .

if possible could you please share the device tree configurations for bluetooth .

There will be a default driver give from nxp,
mlan0. It will compatible for wifi and bt. Did you try those default modules

[naresh_nakka]

Hi ,

yes , we used  default sdio.c driver for wifi [drivers/net/wireless/marvell/mwifiex/sdio.c ]

and for BT we used hci_marvel.c 

configured in device tree as :

WIFI:

&sdhci2 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_mmc2_pins_default>;
bus-width = <4>;
non-removable;
ti,fails-without-test-cd;
cap-power-off-card;
keep-power-in-suspend;
ti,driver-strength-ohm = <50>;
assigned-clocks = <&k3_clks 157 158>;
assigned-clock-parents = <&k3_clks 157 160>;

##address-cells = <1>
#size-cells = <0>;

{

wlcore: wlcore@2 {
compatible = "marvell,sd8897";
reg = <2>;
pinctrl-names = "default";
pinctrl-0 = <&main_wlirq_pins_default>;
interrupt-parent = <&main_gpio0>;
interrupts = <72 IRQ_TYPE_EDGE_FALLING>;
};

BT :

&main_uart2 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_uart2_pins_default>;

bluetooth {
status = "okay";
compatible = "mrvl,88w8897";
max-speed = <2000000>;

};
};

• WiFI is working fine but BT getting issues .

Thanks,

Naresh

Hi Nxp,

any update , please help me on this .

Hi All 

I found the fix, this issues because of power down pin

[sam_yu]

hi vinothkumars

I encountered the same problem. Could you please explain in detail how you handled it
