Edition 8 – 2nd Stage Bootloader#EN – 2011/07
1 Overview
The 2nd stage bootloader is necessary to setup a dual port memory and to offer functionalities to get a
netX based hardware basically running and being able to download firmware files larger than 64kB via
DPM.
File names:
NETX50-BSL.bin for netX 50 based hardware
NETX100-BSL.bin for netX 100/500 based hardware
1.1 Features
Bootloader program Size < 64 Kbyte binary code to allow loading via DPM on netX100/500
Serial COM support
USB / CDC support
DPM support (including host interrupt enabled in DPM mode)
Security FLASH read / write access to user data area
File System FAT based (format / read / write) on serial flash only
Standard DPM layout for "System Channel" and "Handshake Channel"
(like defined in netX DPM Manual)
Extended read and write mailboxes for faster firmware download
System channel hardware information handling
Hardware independent (executed in netX internal memory)
Bootloader Update
File System Restore from SD/MMC (SDHC and SDXC cards are not supported)
License Update
ISA, DPM and PCI support
1.2 Limitations
The bootloader does not include a FTL (Flash Translation Layer) and limited to a FAT file
system on the serial flashes only.
Wear-leveling is not available
For entering USB bootmode of the 2nd stage loader, it is necessary to add an additional
jumper/switch (see netX ROM Loader documentation on how to enter extension bus bootmode,
to design your hardware)
Ethernet support not included
DMA data transfer not included
Firmware cannot be loaded into internal RAM, as this is used by Bootloader
Only serial flashes with the feature "erase single pages" are supported (see list in appendix)
License codes currently not readable on a netX50 based hardware
License Updates can not be executed on a netX50 / netX10 based hardware
SDRAM and DPM cannot be used simultaneously on netX10

2nd Stage Bootloader Bootloader Functions •6
Hilscher Gesellschaft für Systemautomation mbH – Rheinstr. 15 – D 65795 Hattersheim
Edition 8 – 2nd Stage Bootloader#EN – 2011/07
2 Bootloader Functions
2.1 Overview
The loader is executed from the netX internal RAM, because this is always known and makes
the loader independent from the hardware.
To be able to start the 2nd stage bootloader via the DPM, the DPM area must be 64 Kbyte.
Otherwise the netX registers, necessary to restart the netX ROM loader to load the 2nd stage
loader, are not reachable.
The 2nd stage loader creates a "System Channel" and a "Handshake Channel" at DPM offset
0x0 to 0x2FF like defined in the "netX DPM Interface Manual".
The rest of the DPM is used as a separate mailbox system. The mailboxes do not include the
standard administration data (pending packets) and consist only of the raw packet data. The
mailbox size differs from the standard channel mailboxes:
- The size of the new send mailbox is calculated in the following way:
SendMBX size = DPM size - Size of std. channels - Fixed size new RecvMBX
Example:
DPM size = 8192 Byte (0x2000)
Std channel size = 768 Byte (0x300)
Std. Recv MBX size = 124 Byte (NETX_SYSTEM_MAILBOX_MIN_SIZE)
==> Send MBX size = 8192 - 768- 124 = 7300 Byte (0x1C84)
- The new mailbox system has separate handshake pairs in the standard "System Channel"
handshake cell (offset 0x200 in the DPM).
HSF_EXT_SEND_MBX_CMD / NSF_EXT_SEND_MBX_ACK = Bit 6 and
HSF_EXT_RECV_MBX_ACK / NSF_EXT_RECV_MBX_CMD = Bit 7.
- The download via the extended mailbox system is done by using standard rcX packets. Except
the data packet size is adjusted to the extended mailbox size
