BL808学习日志-2-LVGL for M0 and D0

一、lvgl测试环境

        对拿到的M1S_DOCK开发板进行开发板测试，博流的官方SDK是支持M0和D0两个内核都进行测试的；但是目前只实现了M0的LVGLBenchmark，测试D0内核中发现很多莫名其妙的问题。一会详细记录。

        使用的是开发板自带的SPI显示屏，280*240分辨率。

二、M0内核lvgl测试

        使用官方默认的SDK进行编译会报错缓存不够，按照下列方式修改SDK中的.ld内存分布文件

/bouffalo_sdk/bsp/board/bl808dk/bl808_flash_m0.ld文件。主要目的就是修改ram_memory的大小，把ram_wifi的大小暂时调整为0，因为目前官方SDK无法启用无线功能。如果测试过程中卡住，就是ram_memory太小了，缓存不够使用了，调大即可。

}

        修改完成后最好把LP内核的内存分布文件也修改一下。这里引申出一个问题，就是内存的分布肯定是LP和M0内核共享OCRAM+WRAM，但是不知道两个内核的itcm_memory 和dtcm_memory的大小是不是要按照规格书改成32K+16K，官方默认的大小是20K+4K，搞不懂是什么用意。而且两个内核的部分区域在官方SDK中竟然重叠了，好奇怪。对于初学者来说，实在是头大，官方也没有任何说明。

        这里直接贴图一个成绩。

三、D0内核调试挖坑！！！

        测试D0内核花费了3天时间也没搞定，总是进入初始化以后，直接就卡屏卡死了。因为在假期，没带DEBUG工具，只能随便打点测试了一下；

        1.SPI1无法启用

按照官方SDK进行测试，发现根本没有使用SPI1，而且在lcd_spi_hard_4_init(lcd_spi_hard_4_init_t *dbi_parra)初始化过程中，spi_hd = bflb_device_get_by_name(LCD_SPI_HARD_4_NAME);得到的是spi0。。。

int lcd_spi_hard_4_init(lcd_spi_hard_4_init_t *dbi_parra)
{/* spi */struct bflb_spi_config_s spi_cfg = {.freq = dbi_parra->clock_freq,.role = SPI_ROLE_MASTER,.mode = SPI_MODE3,.data_width = SPI_DATA_WIDTH_8BIT,.bit_order = SPI_BIT_MSB,.byte_order = SPI_BYTE_LSB,.tx_fifo_threshold = 0,.rx_fifo_threshold = 0,};/* dma cfg */struct bflb_dma_channel_config_s dma_spi_tx_cfg = {.direction = DMA_MEMORY_TO_PERIPH,.src_req = DMA_REQUEST_NONE,.dst_req = DMA_REQUEST_SPI0_TX,.src_addr_inc = DMA_ADDR_INCREMENT_ENABLE,.dst_addr_inc = DMA_ADDR_INCREMENT_DISABLE,.src_burst_count = DMA_BURST_INCR4,.dst_burst_count = DMA_BURST_INCR4,.src_width = DMA_DATA_WIDTH_16BIT,.dst_width = DMA_DATA_WIDTH_16BIT,};pixel_format = dbi_parra->pixel_format;#if (SPI_FIFO_WIDTH_VARIABLE_SUPPORT)/* SPI support burst*4 */spi_cfg.tx_fifo_threshold = (2 * 4 - 1);spi_cfg.rx_fifo_threshold = (2 * 4 - 1);spi_cfg.byte_order = SPI_BYTE_MSB;
#elifspi_cfg.tx_fifo_threshold = 4 - 1;spi_cfg.rx_fifo_threshold = 4 - 1;
#endifspi_hd = bflb_device_get_by_name(LCD_SPI_HARD_4_NAME);/* CS and DC pin init */gpio = bflb_device_get_by_name("gpio");bflb_gpio_init(gpio, LCD_SPI_HARD_4_PIN_CS, GPIO_OUTPUT | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_1);bflb_gpio_init(gpio, LCD_SPI_HARD_4_PIN_DC, GPIO_OUTPUT | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_1);LCD_SPI_HARD_4_CS_HIGH;LCD_SPI_HARD_4_DC_HIGH;if (spi_hd->idx == 0) {bflb_gpio_init(gpio, LCD_SPI_HARD_4_PIN_CLK, GPIO_FUNC_SPI0 | GPIO_ALTERNATE | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_2);bflb_gpio_init(gpio, LCD_SPI_HARD_4_PIN_DAT, GPIO_FUNC_SPI0 | GPIO_ALTERNATE | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_2);}
#if defined(GPIO_FUNC_SPI1)else if (spi_hd->idx == 1) {bflb_gpio_init(gpio, LCD_SPI_HARD_4_PIN_CLK, GPIO_FUNC_SPI1 | GPIO_ALTERNATE | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_2);bflb_gpio_init(gpio, LCD_SPI_HARD_4_PIN_DAT, GPIO_FUNC_SPI1 | GPIO_ALTERNATE | GPIO_PULLUP | GPIO_SMT_EN | GPIO_DRV_2);}#endif/* spi init */bflb_spi_init(spi_hd, &spi_cfg);/* spi enabled continuous mode */// bflb_spi_feature_control(spi_hd, SPI_CMD_SET_CS_INTERVAL, true);if (pixel_format == LCD_SPI_LCD_PIXEL_FORMAT_RGB565) {dma_spi_tx_cfg.src_width = DMA_DATA_WIDTH_16BIT;dma_spi_tx_cfg.dst_width = DMA_DATA_WIDTH_16BIT;}if (spi_hd->idx == 0) {dma_spi_tx_cfg.dst_req = DMA_REQUEST_SPI0_TX;spi_tx_fifo_address = DMA_ADDR_SPI0_TDR;}
#if defined(DMA_REQUEST_SPI1_TX)else if (spi_hd->idx == 1) {dma_spi_tx_cfg.dst_req = DMA_REQUEST_SPI1_TX;spi_tx_fifo_address = DMA_ADDR_SPI1_TDR;}
#endif/* dma init */spi_dma_hd = bflb_device_get_by_name(LCD_SPI_HARD_4_DMA_NAME);bflb_dma_channel_init(spi_dma_hd, &dma_spi_tx_cfg);/* dma int cfg */bflb_dma_channel_irq_attach(spi_dma_hd, spi_dma_callback, NULL);return 0;
}

按照device_table.c文件中，竟然没有规定spi1..........，也没有规定DMA2的对应0-7个通道，但是却规定了DMA0的0-7个通道，官方datasheet中DMA0和DMA1只有一个通道。8个通道的寄存器基地址都是DMA0_BASE(  #define DMA0_BASE ((uint32_t)0x2000c000)),在else这个分支里面竟然中断号都是0XFF,真是被这SDK搞懵了。看这样子好像官方并不想让使用spi1来使用？？？？？这个问题等待后续解决。

{ .name = "spi0",.reg_base = SPI0_BASE,
#if defined(CPU_M0) || defined(CPU_LP).irq_num = BL808_IRQ_SPI0,
#else.irq_num = 0xff,
#endif.idx = 0,.dev_type = BFLB_DEVICE_TYPE_SPI,.user_data = NULL 
},{ .name = "dma0_ch0",.reg_base = DMA0_BASE + 1 * DMA_CHANNEL_OFFSET,
#if defined(CPU_M0) || defined(CPU_LP).irq_num = BL808_IRQ_DMA0_ALL,
#else.irq_num = 0xff,
#endif.idx = 0,.sub_idx = 0,.dev_type = BFLB_DEVICE_TYPE_DMA,.user_data = NULL 
},

 四、引申出来的RAM分配问题

        下面贴一下官方的SDK中定义的分配方案，看的我脑袋大，有点看不懂能不能这样使用，或者是这样使用会不会出现冲突。(0x62020000的意思是使用chache访问，和直接访问0x2202000是一个意思，但是nocache_ram_memory区域必须使用0x22034000直接访问，不能使用cache访问）。

        1.M0的ram_memory区域，ram_memory  (!rx) : ORIGIN = 0x6202A000, LENGTH = 24K，也就是0x2202A000-0x2203000,但是LP内核的itcm_memory (rx)  : ORIGIN = 0x2202C000, LENGTH = 16K，也就是0x2202C000-0x2203000;

        2.LP内核区域的dtcm_memory (rx)  : ORIGIN = 0x22030000, LENGTH = 16K和M0内核的ram_wifi  (wxa)   : ORIGIN = 0x22030000, LENGTH = 160K - __EM_SIZE冲突，虽然LP内核内部没有cache功能，但是也好奇怪为什么还会划分idata和ddata这两个区域。

        3.我自己曾经尝试过按照不冲突的RAM地址升序顺序和严格按照手册所写的itcm和dtcm大小进行内存划分，没有发现明显区别，coremark和lvgl都没有任何提升。看看后续如何理解这个问题和解决问题。

LP-MEMORY
{fw_header_memory  (rx)  : ORIGIN = 0x58020000 - 0x1000, LENGTH = 4Kxip_memory  (rx)  : ORIGIN = 0x58020000, LENGTH = 1Mitcm_memory (rx)  : ORIGIN = 0x2202C000, LENGTH = 16Kdtcm_memory (rx)  : ORIGIN = 0x22030000, LENGTH = 16Knocache_ram_memory (!rx) : ORIGIN = 0x22030000, LENGTH = 0Kram_memory  (!rx) : ORIGIN = 0x22034000, LENGTH = 16Kxram_memory  (!rx) : ORIGIN = 0x40000000, LENGTH = 16K

}

        还是希望官方能够多给点文档看啊，linux下的M1S_DOCK_SDK好像就有很多正常的功能寄存器，还有库文件，我看文件抬头都是博流写的，真的是无语了。

        后续还是在Linux下使用M1S_DOCK_SDK开发吧，官方的库我实在是搞不懂。浪费精力。
