修改 uboot 的 mmc_startup 中
MMC_RSP_R6 修改 为 MMC_RSP_R4 即可识别EMMC
修改 uboot 中 sunxi_sprite_download_boot0 从介质2 改介质 0 ， 即可完成 PhoenixSuit 烧录到EMMC 并启动进入系统。
怎么说呢，荔枝派ZERO 老当益壮。

让T113-S3的TVIN吃上trecorder的本地预览套餐发布在 MR Series
如题， T113-S3的TVIN 功能令人垂涎。我想呢，看看本地预览咯。
但是这个trecorder 一开，给你提示：
[TR_ERR][VportInit] unknow camera type is sunxi-tvd
然后就没有然后了。
没关系，定位一下位置:
啊原来是这样呢，
那我试试给它赋予USB摄像头的属性呢？ 比如这样：
非常惊喜的就是 ，真的可以跑，
看视频：
完结。
当前需要说前提：
内核的 CONFIG_VIDEO_SUNXI_TVD 要开。
设备树节点要开。&tvd { tvd_sw = <1>; tvd_interface = <0>; tvd_format = <0>; tvd_system = <1>; tvd_row = <1>; tvd_column = <1>; tvd_channel0_en = <1>; tvd_channel1_en = <0>; tvd_channel2_en = <0>; tvd_channel3_en = <0>; /*tvd_gpio0 = <&pio PD 22 GPIO_ACTIVE_HIGH>;*/ /*tvd_gpio1 = <&pio PD 23 GPIO_ACTIVE_HIGH>;*/ /*tvd_gpio2 = <&pio PD 24 GPIO_ACTIVE_HIGH>;*/ /* dc1sw-supply = <®_dc1sw>;*/ /* eldo3-supply = <®_eldo3>;*/ /*tvd_power0 = "dc1sw"*/ /*tvd_power1 = "eldo3"*/ }; &tvd0 { used = <1>; agc_auto_enable = <1>; agc_manual_value = <64>; cagc_enable = <1>; fliter_used = <1>; };recorder.cfg可以用我的,分辨率根据自己摄像头自己改一下吧：
recorder.cfg运行的时候执行：
trecorderdemo 0
就行啦舒服一下。大佬们试试看咯！

为了摆脱TINA-BSP的磁盘噩梦能舒服地只编译LVGL8在D1S/D1上面肆意玩耍发布在 MR Series
但凡拿到了BSP的伙计们，没有开会员网速太慢或者啥的，总是会砸桌子，毕竟BSP辣么大！
但凡拿到了BSP的伙计们并且编译了BSP，硬盘没有买新的，虚拟机都装了，磁盘不够大，编译到一半总是会砸桌子，毕竟BSP编译后辣么大！du -sh 20多个GB咱就是说，单独拿出来make 一下不就行了么
这里分享一下包包：
lv_examples_lvgl8_integrate_compile_small.tar.gz
这里，G2D 双缓冲 全给上了。怎么用呢？
很简单，释放出来， cd lv_examples/src make -jx （x喜欢多少随意）然后就可以在大佬们给的固件烧录后的机器上，舒服地搞上LVGL8 啦，还有2D加速还能随便旋转，还有双缓冲，美滋滋么。
舒服，试一下！

因为喜欢用ADB，因为不喜欢插拔TF卡，所以D1直接用PhoenixSuit烧录TF(SDNAND)发布在 MR Series
如题
因为不喜欢插拔卡搞来搞去，喜欢直接USB插上直接干活烧录到底，
那就，看下D1怎么搞TF直接通过PhoenixSuit烧录 TF卡或者SDNAND第一步，看启动过程的LOG：

try card 2
set card number 2
get card number 2
这里默认从card 2 开始
那么咱就先试试看，直接从card 0 行不行？
直接搜索到代码中定位到的是：

中的接口：int sunxi_sprite_mmc_probe(void) { #ifndef CONFIG_MACH_SUN50IW11 return sdmmc_init_for_sprite(0, 2); #else int workmode = uboot_spare_head.boot_data.work_mode; if (workmode == WORK_MODE_CARD_PRODUCT) return -1; else return sdmmc_init_for_sprite(0, 0); #endif }这里 CONFIG_MACH_SUN50IW11 没有定义
默认是执行 return sdmmc_init_for_sprite(0, 2);那么咱就是说，直接改return sdmmc_init_for_sprite(0, 0); 试试看？
好的说改就改了。
int sunxi_sprite_mmc_probe(void) { #ifndef CONFIG_MACH_SUN50IW11 return sdmmc_init_for_sprite(0, 0); #else int workmode = uboot_spare_head.boot_data.work_mode; if (workmode == WORK_MODE_CARD_PRODUCT) return -1; else return sdmmc_init_for_sprite(0, 0); #endif }改动了下，直接烧录测一下：

在TinaV2.2 D1s上面搞LVGL8去调用G2D旋转让LVGL8的软件旋转再见发布在 MR Series
如题
竖的屏幕横过来用很难受，要转图像，很烦的。

那么咱就是说，转一波？
很难受的一点是G2D这设置没找到哪里是完整的配置案例，
一波摸索以后是这样的：disp_rotation_used = <1>; degree0 = <3>; fb0_format = <0>; fb0_buffer_num = <2>; fb0_pixel_sequence = <3>; fb0_scaler_mode_enable = <1>; fb0_width = <854>; fb0_height = <480>; /*read from lcd*/ fb1_format = <0>; fb1_width = <0>; fb1_height = <0>; chn_cfg_mode = <0>;当然 内核的g2d 配置项目要开启：
编译一波测试一下吧，
舒服啦

请教下大佬， 模仿esd程序进行中断中修改亮度操作，
可以写入亮度成功，也可以读到东西，但是中断就无法重新进入了。
是否有什么注意到的地方。static s32 lcd_set_oled_bright(u32 sel,u32 bright) { s32 ret = 0; u8 result[16] = {0}; s32 nump = 1; ret = sunxi_lcd_dsi_dcs_read(0, 0x54, result,&nump); dsi_dcs_wr_1para(sel, 0xFE, 0x00); //{ 0xFE,1,{0x00} }, dsi_dcs_wr_1para(sel, 0x51, 0x50); printk(KERN_WARNING "wwwwwwwwwwww lcd_set_oled_bright :bright = %d read result :%02x \n",bright,result[0]); return 0; } /*此处省略*/ struct __lcd_panel rm69330_139_panel = { /* panel driver name, must mach the name of * lcd_drv_name in sys_config.fex */ .name = "rm69330_139", .func = { .cfg_panel_info = lcd_cfg_panel_info, .cfg_open_flow = lcd_open_flow, .cfg_close_flow = lcd_close_flow, .lcd_user_defined_func = lcd_user_defined_func, .set_bright = LCD_set_bright, .esd_check = lcd_esd_check, .reset_panel = lcd_reset_panel, .set_esd_info = lcd_set_esd_info, .oled_set_bright = lcd_set_oled_bright, }, };#if defined(__LINUX_PLAT__) static irqreturn_t disp_lcd_event_proc(int irq, void *parg) #else static irqreturn_t disp_lcd_event_proc(void *parg) #endif { struct disp_device *lcd = (struct disp_device *)parg; struct disp_lcd_private_data *lcdp = NULL; struct disp_manager *mgr = NULL; #if defined(SUPPORT_EINK) && defined(CONFIG_EINK_PANEL_USED) struct disp_eink_manager *eink_manager = NULL; #endif u32 hwdev_index; u32 irq_flag = 0; unsigned int panel_extend_dirty; unsigned int panel_extend_modify_oledbright; unsigned long flags; if (lcd == NULL) return DISP_IRQ_RETURN; hwdev_index = lcd->hwdev_index; lcdp = disp_lcd_get_priv(lcd); if (lcdp == NULL) return DISP_IRQ_RETURN; #if defined(SUPPORT_EINK) && defined(CONFIG_EINK_PANEL_USED) eink_manager = disp_get_eink_manager(0); if (eink_manager == NULL) return DISP_IRQ_RETURN; #endif if (disp_al_lcd_query_irq (hwdev_index, LCD_IRQ_TCON0_VBLK, &lcdp->panel_info)) { #if defined(SUPPORT_EINK) && defined(CONFIG_EINK_PANEL_USED) eink_display_one_frame(eink_manager); #else int cur_line = disp_al_lcd_get_cur_line(hwdev_index, &lcdp->panel_info); int start_delay = disp_al_lcd_get_start_delay(hwdev_index, &lcdp->panel_info); #if defined(CONFIG_DISP2_LCD_ESD_DETECT) if (lcdp->lcd_panel_fun.esd_check && lcdp->lcd_panel_fun.reset_panel) { ++lcdp->esd_inf.cnt; if (cur_line < 2 && !atomic_read(&lcdp->lcd_resetting) && lcdp->esd_inf.cnt >= lcdp->esd_inf.freq) { disp_al_lcd_disable_irq(hwdev_index, LCD_IRQ_TCON0_VBLK, &lcdp->panel_info); if (!lcdp->esd_inf.esd_check_func_pos || lcdp->lcd_panel_fun.esd_check(lcd->disp)) { /*request reset*/ atomic_set(&lcdp->lcd_resetting, 1); schedule_work(&lcdp->reflush_work); printk(KERN_WARNING "wwwwwwwwwwww lcd_esd_check disp_lcd_event_proc 1633 \n"); } disp_al_lcd_enable_irq(hwdev_index, LCD_IRQ_TCON0_VBLK, &lcdp->panel_info); printk(KERN_WARNING "wwwwwwwwwwww after lcd_esd_check disp_lcd_event_proc 1635 \n"); lcdp->esd_inf.cnt = 0; } } #endif mgr = lcd->manager; if (mgr == NULL) { printk(KERN_WARNING "wwwwwwwwwwww after if (mgr == NULL) 1644 \n"); return DISP_IRQ_RETURN; } if (cur_line <= (start_delay - lcdp->judge_line)) sync_event_proc(mgr->disp, false); else sync_event_proc(mgr->disp, true); #endif } else { irq_flag = disp_al_lcd_query_irq(hwdev_index, LCD_IRQ_TCON0_CNTR, &lcdp->panel_info); irq_flag |= disp_al_lcd_query_irq(hwdev_index, LCD_IRQ_TCON0_TRIF, &lcdp->panel_info); if (irq_flag == 0) goto exit; if (disp_al_lcd_tri_busy(hwdev_index, &lcdp->panel_info)) { /* if lcd is still busy when tri/cnt irq coming, * take it as failture, record failture times, * when it reach 2 times, clear counter */ lcdp->tri_finish_fail++; lcdp->tri_finish_fail = (lcdp->tri_finish_fail == 2) ?
