MSP430FR6043: BSL upgrade

Yale Li 李耀先

Part Number: MSP430FR6043

Hi team,

Here's two issues from the customer may need your help:

1. The BSL listed in the slau550aa documentation cannot be found in the MSP430BSL_1_02_00_01.zip file. As shown below.

2. The FRAM space of FR6043 is: 6000~15FFF, of which F000- OXFFFF is defined as bootloader.

When using the MSP430FRBoot_1_03_00_00 host routine to upgrade, the APP.TXT cannot be loaded, and the size is about 45K. But there is no problem with the smaller program.

Is it because after the bootloader is divided, the addresses before and after can not meet the 40K continuous address, which causes it to fail to load.

Thanks.

Best Regards,

Yale

    Hello Yale,

    1. The exact version of the BSL loaded into MSP430FR6043 is not provided in the CUSTOMBSL downloads folder, as the BSL in this device is in ROM and cannot be changed or updated.

    2. As per 1, the BSL in this device is in ROM and cannot be changed, thus you cannot use that section of memory for MSPFRBOOT. MSPFRBOOT resides completely in application memory space. Please see the MSPFRBOOT documentation for setting up your linker file appropriately for it to work. The boatloader really should be 45k memory though. It should be made as small as possible and load up your main application.
