LPCScrypt - Programming via USB

Hello,

I have problem with programming LPC1853 via USB.

My environment : Keil uVision, LPCScrypt 1.8.0, srec_cat (SRecord).

In my HW I have LPC1853 and external SPIFI flash. I would like to exchange code via USB0.

LPCScrypt can't program all memories (two internal memory Banks and ext. flash) . I need to split one final hex file into 4 small peaces - BankA, BankB, SPIFI, EEPROM.

Keil recommended to use srec_cat tool to do it. It works fine. I can program via LPCScypt (USB0) SPIFI and EEPROM, but I have a problem with internal flash Banks.

LPCSrypt shows error :

But I tried to program the same hex (WPS15_BankA.hex) via J-Flash (and JTAG) and it works fine. It adds checksum for this bank. And after programming a both banks via J-Flash a device works fine.

LPCScrypt has problem with the size, although I divided internal flash according to the instructions on the 2 banks (each 256kB).

PS. Keil instruction how to use srec_cat tool :

GENERAL: SPLITTING HEX FILES

My instructions to split hex :

srec_cat.exe -Output_Block_Size=32 -address-length=4 .\Obj\WPS15.hex -Intel -crop 0x1A000000 0x1A040000 -o .\Obj\WPS15_BankA.hex -Intel
srec_cat.exe -Output_Block_Size=32 -address-length=4 .\Obj\WPS15.hex -Intel -crop 0x1B000000 0x1B040000 -o .\Obj\WPS15_BankB.hex -Intel

Looks like you have a HEX file and not a BINARY file... A hex file is an ascii encoding of binary data. A binary file is just the exact binary data you want written to the memory. LPCScrypt needs binary data, not ascii.

Hi Mariusz Wlodarczyk,

LPCScrypt can be used to download either plain binary files or binary files wrapped with a header, and other format files are not available.
Have a great day,
