FlexCAN过滤器在所有配置上都是重复的

你好，

我在SPC5 Studio 3.4.3上使用SPC56EL60的FlexCAN，我想为每个人定义过滤器。我为每个包含不同过滤器的配置创建了一个配置。 CAN1有16个滤波器，从0x200到0x20F，CAN2有16个滤波器，从0x400到0x40F。
  - ＆GT;第一个问题：所有过滤器都在所有配置中合并（CAN1过滤器配置为0x200到0x20F和0x400到0x40F）。我必须手动编辑can_lld_cfg.c。
  - ＆GT;第二个问题：两个FlexCAN的Rx邮箱号码都是固定的。代码生成器不允许为每个FlexCAN设置特定的编号。
  - ＆GT;第3个问题：将Rx邮箱号设置为16不会影响函数can_lld_is_rx_nonempty，该函数仅在不使用CAN_ANY_MAILBOX常量时检查前8个邮箱。

Hello,

I'm using both FlexCAN of SPC56EL60 on SPC5 Studio 3.4.3 and I wanted to define filters for each of them. I created a config for each of them containing different filters. CAN1 has 16 filters from 0x200 to 0x20F and CAN2 has 16 filters from 0x400 to 0x40F.
--> 1st problem: all filters are merged in all config (CAN1 filters config was 0x200 to 0x20F AND 0x400 to 0x40F). I had to edit can_lld_cfg.c manually.
--> 2nd problem: the Rx mailbox number is fixed for both FlexCAN. The code generator does not allow to set a specific number for each FlexCAN.
--> 3rd problem: setting Rx mailbox number to 16 does not affect the function can_lld_is_rx_nonempty which only checks the first 8 mailboxes when not using the CAN_ANY_MAILBOX constant.
