[DM15L] Unresponsive after update attempt

Post by elgarak »

I've tried updating my HP15L (after having successfully done it with my DM41L). It broke off with an error message (which I foolishly failed to record). No beep upon pressing reset.

Now the calc is unresponsive. Doesn't come on. Display stays clear. Tried changing the battery. Battery is full.

Help, please?

Was able to recover the response after I started the sync and pressed reset on the calc:

Code: Select all

Read bootcode version: 2
7
Read part ID: LPC1115.../303, 64 kiB FLASH / 8 kiB SRAM (0x00050080)
Will start programming at Sector 1 if possible, and conclude with Sector 0 to ensure that checksum is written last.
Erasing sector 0 first, to invalidate checksum. Wrong answer on Erase-Command
