The communication protocol for normal PXI commands is documented below. The size of cmd_buf is calculated from the cmd_hdr. Total size for command header + buffer must be at most 0x40 bytes, otherwise Process9 will panic.
The communication protocol for normal PXI commands is documented below. The size of cmd_buf is calculated from the cmd_hdr. With newer FIRM the total size for command header + buffer must be at most 0x40 bytes, otherwise Process9 will panic.
