hello, good day, I am making an example with a 5500 chip in esp32 with the socketioclient library, but when I want to send the json to my server, they are only left on the waiting list and I don't know what is happening to me, before all this an error message about invalid mbox appeared and I added the following line of code esp_netif_init(); and it was fixed, but once entering the loop the following happens:
serial monitor:

then the loop remains without emitting it just remains as shown above

If someone could help me, it would be very helpful. Thank you. I'm new to ethernet connectivity. I hope you understand.
I`m using the Atmel KMS/DRM LCD driver to make it work a custom LCD (ST5651CB + ST5021CB) that I have at home from another project that I wanted to use. So, in order to speed up the development strategy I have divided the problem into several parts which are detailed below.
I have started by integrating the TSC2007 touchscreen driver with successful results, as voltage fluctuations are detected on the screen when it is touched, according to the normal operation after the inclusion of the relevant node in the corresponding i2c bus.
Subsequently, the node for the backlight has been included, making use of the pwm-backlight kernel driver. Also in this case it is fully functional, being able to activate or deactivate it on demand, as well as change the brightness levels (which have been previously defined with the values that oscillate in the interval [0,255]).
Once this has been done, the timing analysis of the panel in SYNC mode has been undertaken using the ST5651CB specification in which this is detailed, to populate the node that makes use of the simple-panel driver of the kernel (to which the backlight previously discussed has been assigned).
(root node)
....
/* Screen brightness */
backlight: backlight {
compatible = "pwm-backlight";
pwms = <&hlcdc_pwm 0 50000 0>;
brightness-levels = <0 4 8 16 32 64 128 255>;
default-brightness-level = <7>;
status = "okay";
};
/* ST5651CB + ST5021CB TFT LCD */
panel: panel {
compatible = "simple-panel";
backlight = <&backlight>;
width-mm = <155>; /* Active area (W) 154.21 */
height-mm = <86>; /* Active area (H) 85.92 */
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
/* SYNC mode */
panel-timing {
clock-frequency = <65000000>; /* Panel clock (Hz) */
hactive = <1024>; /* Active frame width (px) */
vactive = <768>; /* Active frame height (px) */
hfront-porch = <160>; /* Horizontal front porch timing (px) */
hsync-len = <160>; /* HSD blanking (px) */
hback-porch = <160>; /* Horizontal back porch timing (px) */
vfront-porch = <15>; /* Vertical front porch timing (lines) */
vsync-len = <23>; /* VSD blanking (lines) */
vback-porch = <15>; /* Vertical back porch timing (lines) */
pixelclk-active = <0>; /* Data driving on falling edge */
hsync-active = <0>; /* Horizontal sync pulse (low) */
vsync-active = <0>; /* Vertical sync pulse (low) */
de-active = <0>; /* Data enable (low) */
};
port#0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
panel_input: endpoint#0 {
reg = <0>;
remote-endpoint = <&hlcdc_panel_output>;
};
};
};
...
Also in the kernel argument line (using U-Boot bootargs) I`m specifying the mode by supplying video=Unknown-1:1024x768-16
Finally, and I have conglomerated each of these parts to achieve the final goal, populating the hlcdc node in the device tree and having the LCD functional.
(apb node)
...
hlcdc: hlcdc#f0000000 {
u-boot,dm-pre-reloc;
status = "okay";
hlcdc-display-controller {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb666 &pinctrl_lcd_reset>;
port#0 {
#address-cells = <1>;
#size-cells = <0>;
hlcdc_panel_output: endpoint#0 {
reg = <0>;
remote-endpoint = <&panel_input>;
};
};
};
hlcdc_pwm: hlcdc-pwm {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcd_pwm>;
#pwm-cells = <3>;
};
};
...
The problem is that this strategy does not seem to work because, as mentioned above, because I only have the backlight and the touchscreen functional, but nothing is displayed on the screen.
The question is basically if this guide to integrate a custom LCD in linux is correct or if it has been wrong somewhere.
I have GPIO-expnader tca6424 on my board. Pin 17 supplies another chips. I need to power off this chips in the "suspend-to-RAM" mode. I described it in dts file:
hu_u1740: tca6424_hu_u1740#22 {
compatible = "ti,tca6424";
reg = <0x22>;
gpio-controller;
#gpio-cells = <2>;
regulator#17 {
regulator-min-microvolt = <33000000>;
regulator-max-microvolt = <3300000>;
regulator-always-on;
regulator-name = "pw_bt";
enable-active-high;
regulator-state-mem {
regulator-off-in-suspend;
};
};
};
I tried pin 17 as regulator but it doesn't work. If is there ready way or i should write own driver?
I am trying to interface Artix-7 FPGA with CC3200MOD for SPI transfers. CC3200MOD is the slave. I am receiving only '.' on the terminal.
SPI slave program:
void SlaveMain()
{
//
// Initialize the message
//
memcpy(g_ucTxBuff,SLAVE_MSG,sizeof(SLAVE_MSG));
//
// Set Tx buffer index
//
ucTxBuffNdx = 0;
ucRxBuffNdx = 0;
//
// Reset SPI
//
MAP_SPIReset(GSPI_BASE);
//Message("\n\r SPI reset");
// Configure SPI interface
//
MAP_SPIConfigSetExpClk(GSPI_BASE,MAP_PRCMPeripheralClockGet(PRCM_GSPI),
SPI_IF_BIT_RATE,SPI_MODE_SLAVE,SPI_SUB_MODE_3,
(SPI_HW_CTRL_CS |
SPI_4PIN_MODE |
SPI_TURBO_ON |
SPI_CS_ACTIVELOW |
SPI_WL_8));
Message("\n\rSPI configured");
//
// Register Interrupt Handler
//
MAP_SPIIntRegister(GSPI_BASE,SlaveIntHandler);
//
// Enable Interrupts
//
MAP_SPIIntEnable(GSPI_BASE,SPI_INT_RX_FULL|SPI_INT_TX_EMPTY);
//
// Enable SPI for communication
//
MAP_SPIEnable(GSPI_BASE);
//Message("\n\rSPI enabled");
/*MAP_SPIReset(GSPI_BASE);
MAP_SPIConfigSetExpClk(GSPI_BASE,MAP_PRCMPeripheralClockGet(PRCM_GSPI),
SPI_IF_BIT_RATE,SPI_MODE_SLAVE,SPI_SUB_MODE_0,
(SPI_HW_CTRL_CS |
SPI_4PIN_MODE |
SPI_TURBO_OFF |
SPI_CS_ACTIVELOW |
SPI_WL_8));
MAP_SPIEnable(GSPI_BASE);
//}*/
}
The SlaveMain() function is called once in the main and then the program goes into a while(1) until SPI interrupt is hit. When SPI interrupt is hit, only '255' is received irrespective of what I transmit from the FPGA.
What can be the issue?
I have platform with MT7620 in MIPS arch. On Platform is instaled OpenWRT. I also use Image Builder to create firmware. Now I whant to enable UART interface in my platform. I think that I must add inode to DT in mt7620.dts file but I do not know what must be the correct syntax. My propozition is below. I also need that UART worked as ttyS0 and console I whant to assigned to ttyS1
So, in file mt7620.dts I whant to add this
chosen {
bootargs = "console=ttyS1,15200";
};
uart#500 {
compatible = "ralink,mt7620a-uart", "ralink,rt2880-uart", "ns16550a";
reg = <0x500 0x100>;
interrupt-parent = <&intc>;
interrupts = <5>;
reg-shift = <2>;
pinctrl-names = "default";
pinctrl-0 = <&uartf_pins>;
status = "ok";
};
Please tell me whether above syntax is correct ?
Main library (dtsi) its following inode UART
uart#500 {
compatible = "ralink,mt7620a-uart", "ralink,rt2880-uart", "ns16550a";
reg = <0x500 0x100>;
resets = <&rstctrl 12>;
reset-names = "uart";
interrupt-parent = <&intc>;
interrupts = <5>;
reg-shift = <2>;
status = "disabled";
};
EITD
The answer is simply. It should be add inode to *.dts
uart#500
{
status = "okay"
}
That is all, because all parameters have been define in *.dtsi file.
