Other Parts Discussed in Thread: MSP430F5438, MSP430F5438A
Hi,we have the same question that we can't enter the BSL mode when use msp430F5438A,as Jim descreptioned in http://e2e.ti.com/support/microcontrollers/msp430/f/166/t/70308.aspx?pi77810=1 .I fear that no one concerned about that post so I send a new post . At first we can do this with MSP430F5438, beacause this microchip was already end of life,we use MSP430F5438A to instead of it, but we find that we can't upgrade the code though BSL mode. Now we kow that"the 5438A has a bug which the non-A version does not: The low time on TEST must be less that 15 uS", and as Lane Westlund said we can't do this when use PC to upgrade.And we noticed that Lane Westlund suggest we can " make a small program in User Code which simply jumps to 0x1000 at startup, forcing a BSL entrance in any case " . Does it work like a bootlooder , when the MCU powerup the code jump into BSL mode and check whether need to do upgrade , if not it begin to run start main ? We ask for TI department in China , they say they do not have the competence to get the code , and suggest seek for some help form here , can anyone send the code to me , my e_mail is liersong1@163.com . Thank you very much.
