Some examples described herein provide for dynamically reconfiguring a base address register (BAR) of a Peripheral Component Interconnect Express (PCIe) configuration space. In an example, information relating to a BAR of a PCIe configuration space is written to a PCIe extended configuration space of the PCIe configuration space, which is read, by a dynamic BAR module. Respective values are written, by the dynamic BAR module, to bits of the BAR based on the information. After writing by the dynamic BAR module, a set value is attempted to be written to each of address bits of the BAR. Writing the set value to an address bit of the BAR is prevented when the address bit is set to a predefined value. After attempting to write, a read value is read from the bits of the BAR. A base address of memory is written to the BAR based on the read value.
