RM42L432: RM42L432 BOOTLOADER

Weeken Chang

Part Number: RM42L432
Other Parts Discussed in Thread: TMS570LS0432

Hello:
Please tell me what other settings are different between TMS570LS0432 (big-endian (BE32) format.) and RM42L432 (little-endian (LE) mode.) in BOOTLOADER besides this, because I can program BOOTLOADER for TMS570LS0432 However, after modifying the same program to little-endian (LE) mode, the BOOTLOADER program cannot be programmed to RM42L432. What else should I pay attention to? Thank you.

HI Weeken chang,

Can you please tell me which bootloader you are trying to port to the RM42?

CAN or UART or Ethernet or anyother?

I modified it from the UART sample program and changed it to little-endian (LE) mode.

Thank you very much for your assistance

HI Jagadish
This is the setting of bl_link.cmd currently used. Please help to check if there are any setting errors. Thank you.
