原本项目使用GD32F450，uC/OS-III版本为3.04.05；现在需要把芯片更换GD32H7系列，操作系统支不支持了；还是说必须要用最新的uC/OS-III。

GD32 Embedded Builder现在还不支持GD32H7系列MCU软件开发？如何支持GD32H7系列MCU软件开发，

基于 官方提供的关于gd32f4移植netxduo 的底层驱动来 移植gd32h7 目前的移植情况呢 是 开Cache 网络不通 ping不通 不开Cache的情况下 网络是能够ping通的 mpu 配置 mpu_init_struct.region_base_address = 0x30000000; mpu_init_struct.region_size = MPU_REGION_SIZE_32KB; mpu_init_struct.access_permission = MPU_AP_FULL_ACCESS; mpu_init_struct.access_bufferable = MPU_ACCESS_BUFFERABLE; mpu_init_struct.access_cacheable = MPU_ACCESS_NON_CACHEABLE; mpu_init_struct.access_shareable = MPU_ACCESS_NON_SHAREABLE; mpu_init_struct.region_number = MPU_REGION_NUMBER1; mpu_init_struct.subregion_disable = MPU_SUBREGION_ENABLE; mpu_init_struct.instruction_exec = MPU_INSTRUCTION_EXEC_PERMIT; mpu_init_struct.tex_type = MPU_TEX_TYPE0; if defined (__CC_ARM) /*!< ARM compiler */ __attribute__((section (".RAM_D2"))) enet_descriptors_struct rxdesc_tab[ENET_RXBUF_NUM]; /*!< ENET RxDMA descriptor */ __attribute__((section (".RAM_D2"))) enet_descriptors_struct txdesc_tab[ENET_TXBUF_NUM]; /*!< ENET TxDMA descriptor */ __attribute__((section (".RAM_D2"))) uint8_t rx_buff[ENET_RXBUF_NUM][ENET_RXBUF_SIZE]; /*!< ENET receive buffer */ __attribute__((section (".RAM_D2"))) uint8_t tx_buff[ENET_TXBUF_NUM][ENET_TXBUF_SIZE]; /*!< ENET transmit buffer */ RAM_D2地址划分如下： ; RW data - SRAM0(0x30000000) + SRAM1(0x30004000) 16 + 16 = 32kb RW_IRAM4 0x30000000 0x00008000 { *(.RAM_D2) }

请问大佬们在使用GD32H759芯片配置CAN FD时，如何正确配置邮箱过滤器呢？手册上说使用FD帧就无法使用接收FIFO进行过滤。

货量多不多

前端时间在调试 GD32H7 ,可是发现使用TLI 时 还是存在问题，调了很久最后放弃了 由于H7 的架构 有多种内存块， 使用不当就存在问题 开始使用外部RAM存放显存， 一直没成功， 后来没办法使用内部RAM 单显存测试，还是不行，屏幕显示经常有马赛克， 感觉这个TLI 配置起来太麻烦了 有TLI 有2个图层 ， 使用的时候 即使用一个图层 ，2个图层还是必须要都要配置，不配置还不行 因为2个图层后面有个混合 更新输出的时候 也比较扯。 在使用LVGL 时，使用单格全屏显示缓存，我配置了TLI 的2个图层，仅使用1个图层输出， 然后再输出时使用 [color=#dadada][backcolor=#1e1e1e][font=Consolas,][color=#dcdcaa]tli_reload_config[/color][color=#b4b4b4]([/color][color=#dadada]TLI_FRAME_BLANK_RELOAD_EN[/color][color=#b4b4b4]);[/color] [/font][/backcolor][/color] 来触发TLI更新输出，但是有问题，无法显示， 这就很扯，首先也不知道什么时候更新完成？然后调用这个没有效果 有没有H7 的LGVL的例子学习一下？

EXMC初始化之后，对外部SRAM的操作没有效果，以下是代码部分(nor_region传的是EXMC_BANK0_NORSRAM_REGION0)。 请大佬们看看是什么问题。 void exmc_norflash_init(uint32_t nor_region) { exmc_norsram_parameter_struct nor_init_struct; exmc_norsram_timing_parameter_struct nor_timing_init_struct;

通过H7往SD卡写入txt文件，使用读卡器在电脑上看不到该文件，但是在H7上始终可以读取文件，并且也可以查看文件信息；同理，在电脑上创建的文件，在H7上也无法搜索和查看到。不知道是什么原因。

GD32H759IMT6和GD32H759IMT7有啥区别？datasheet上管脚，封装一样的！
