Hi @matthewhuck,
Which steps did you try to enter bootloader mode?
You can try below procedure:
- Power off module. Place a jumper on Prog. Mode Pins to pull GPIO(27) to high (source). The position is highlighted as attached image
- Open bootloader tool (I used Hercules tools) and press reset button on the module
- Check ACK message, the boot loader of the module should go into communication mode. The message like this:
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2
load:0x3fff80c8,len:4
load:0x3fff80cc,len:152
load:0x40078000,len:0
ho 12 tail 0 room 4
load:0x40078000,len:13652
entry 0x40078b24
ÀWSIHÀ
At this point, the module enter bootload mode successfully
