Bootstrap Loader

2/98 Page 11© PEP Modular Computers

4 Command Reference

4.1 Boot Wait

Syntax

bw [<time>]

Description

Without parameters, bw displays the current setting.

For <time> 1, 2, 5, 10, 20 and 50 may be specified as time in seconds. Other values are not supported.

Note:

CPUs without an user LED or without an ABORT button have a BootWaitTime of at least 5 seconds. The Bootstrap

Loader refuses setting a BootWaitTime of 1-2 seconds.

4.2 Load Flash

Syntax

If [-o[=]<offset>] [-u] [-q] [-c] [-m[=]<adr> -l[=]<len>]

Description

Without parameters, the FLASH is loaded using S-records over the term port.

'<offset>' is a signed 32 bit offset which is added to every record and can be used to move the S-records to the FLASH

position.

Note:

This option must be used if S1 or S2 records are used.

'-u' must be used to download over ser0.

'-q' suppress all messages except error messages.

'-c' clears all untouched sectors and leaves no old code fragments.

For a Load Flash from an absolute address, the -m / -l options must be used.

Note:

On CPUs without a ser0 serial connection the Bootstrap Loader will refuse a command including the '-u' option.

4.3 Memory Display

Syntax

md [<adr>]

Description

Without parameters specified, the FLASH contents starting at the beginning of the programmable FLASH area are dis-

played. This function is not limited to FLASH and other address ranges can be specified.

Note:

The ResetPC in FLASH is not identical to the ResetPC from the programming source (S-records memory block).
