The pulsed magnet control system at KEK electron positron injector LINAC operates at every 20 ms to achieve the simultaneous injection for four rings, 2.5 GeV PF, 6.5 GeV PF-AR, 4 GeV SuperKEKB LER and 7 GeV SuperKEKB HER. The system consists of a control PC which operates on the Windows 8.1 platform, in conjunction with a PXIe chassis equipped with a DAC, an ADC and an event timing module. The PXIe DAC board responds to the trigger signal which is generated from the event receiver and sets the current of the pulsed magnet. The current readback value of magent is retrieved from the ADC module. However, the discontinued support of Windows 8.1 and high failure rate require an upgrade of the current system. To reuse current hardware, the upgraded system uses Linux to communicate with PXIe modules and the EPICS driver for PXIe devices is thus required. The development of the new Linux-based pulsed magnet control system is introduced in this work.
