What is the maximum number of capes that can be stacked on a BBB? Of course this would take into account mechanical as well as electrical considerations. For example, the maximum number may be limited by capacitance and timing issues as well as cape ID (I2C addressing) space. A brief explanation of the limitation would be appreciated.
Thanks in advance.
Four. It is described in the System Reference Manual.
maximum number of capes that contain a I2C eeprom for identification is 4, however as many capes as you would like can be added as long as they don’t contain the EEPROMs. this does place the burden of enabling the support for the cape on the user…
Actually, the more you add , the more likely the HDMI will be to get noisy and the eMMC to get flaky.
